How to overcome water obstacles. Crossing over water barriers. a) swim across the river, use air mattresses and cameras

water obstacles very often they can become a problem that is difficult to solve, and in some cases rivers and swamps can cause the trip to be canceled. Also, if the water obstacle is not properly overcome, accidents or health problems can occur. Therefore, it is always necessary to determine the presence of rivers, lakes and swamps on the route map, and if such appear on your way, it is very important to know how to overcome them correctly.
This article presents guidelines to overcome water obstacles, which were developed by V. G. Varlamov.

How to ford the river

Ford- is not deep place in a river that can be crossed on foot or by car. Fording the river is the most common case of crossing. If the river is shallow or very narrow, so that it can be jumped over, then it does not take much effort to overcome such a river. But for wide and deep rivers, you need to know how to choose the right place for a ford. The ford can be found by its external signs: ripples on the surface of the water, the expansion of the river in its straight section, islets, rifts, reaches, shallows, as well as paths and roads that descend to the river.

The figure below shows a generalized scheme of the river, which shows possible depths on the river.

It should be noted that the ford various rivers may be defined differently. So on flat rivers, when choosing a ford, it is necessary to establish the absence of whirlpools, silt, deep pits, snags, mud, flooded trees and other objects that can cause serious complications when crossing the river. But in a mountain river to find a ford along outward signs even more difficult. Here it is necessary to determine the width of the river bed, its possible depth, the state of the bottom and the speed of the current. It is very important to choose the tactics of overcoming the river, i.e. after finding a ford, you need to choose the place of approach and the conditional place of exit to the opposite bank.

If the river is very difficult, then they use a safety rope, which is fastened from the side of the chest with a carabiner to the chest harness. After successfully crossing the river, the participant fastens the rope to a reliable object to help other tourists cross. Holding on to the rope, tourists cross the river facing the current. If the river has a very large current, then you need to attach to the rope with a carabiner or a safety loop. In order not to leave the rope, the last participant unties it and attaches to it, and then with the help of a pole is transported across the river. It is believed that it is safer to wade across the river in clothes and shoes.

How to cross a river over water

You can jump over a small river. And many mountain shallow rivers overcome on protruding stones if they are located in a step or at a distance of a small jump that can be made from a place. If there is no such place, then you can manually throw a few stones. In any case, when crossing rivers, you need to use a pole (stick) for insurance. In some cases, if it is impossible to jump over the river (you have a heavy backpack or the river has a distance that it is already impossible to jump), you can lean on a pole and jump to the opposite bank by pushing off your bank.

The most convenient and safe to eat crossing the river on a log or a tree. In this case place for crossing it is chosen so that it is narrow and has raised banks (so that water does not flood the log). Before the start of the crossing, the log must be strengthened on both sides of the river. To install a log on the other side of the river, a rope is used, with which you can lift it and send it to the other side. Then this rope is tied at the right height above the log to be used as a railing.

The crossing can be done if there is a tree near the river. It is cut in such a way that it falls on the opposite bank. The first participant without a backpack is transported to the opposite bank along the tree and, for reliability, attaches it.

In some cases, a natural blockage can be found on the river, along which it can be crossed. But before that, you need to make sure about its strength.

Although in the Carpathians most of the large mountain rivers are located near settlements, where there are bridges, still the probability of meeting a stormy and deep river is high, especially during the rainy season, when a small stream can turn into a dangerous stream of water. In this case, the crossing is carried out using a stretched rope (or cable). In any case, one of the tourists must ford the river to the opposite bank in order to secure the end of the rope on the other bank. If this cannot be done, then you can try the technique of throwing a rope with an object in order to overwhelm it over a certain support (stone, tree, bushes, rock ledge, etc.). After that, one participant in the hike is transported along the rope to the other side and securely fastens its end. The other end is also firmly fixed.

To do crossing the river on a rope, tourists must fasten to two ropes with carabiners from the chest harness and gazebo. The crossing is carried out feet first if the ropes are strongly inclined towards the opposite bank. And, we cross head first if the stretched ropes have a small angle of slope or sag.
You need to move along the rope in a horizontal position due to your weight. Sometimes an auxiliary rope is used, which is fastened to the carabiners on which the tourist is transported. With the help of an auxiliary rope, other participants can pull the tourist. All accessories and backpacks are transported separately from people.

How to cross rivers and reservoirs on ice

In winter, rivers and lakes are covered with ice, which can be crossed if the ice is strong enough. Therefore, before entering the ice, it is necessary to check its condition and then take all necessary measures safety (loosen the straps of the backpack, set a distance between the participants of 5-7 meters). It is obligatory to have a rope ready when entering the ice and each participant must have a pole. A rope and a pole are needed in case a hiker falls through the ice in order to pull him out of the water.

How to make water crossings

By water, the crossing can be carried out using boats, kayaks, collapsible catamarans, air mattresses, inflatable rafts, home-made wooden rafts. When crossing the water, you must not overload the ship with people and cargo. It is always necessary to check the reliability of the connection and the carrying capacity of swimming facilities before crossing. In stormy weather, the crossing is not possible.

Implementation of the crossing

Swimming is used when it is impossible to use other types of crossing through a reservoir. With such a crossing, it is advisable to use an auxiliary rope, with the help of which people and backpacks are transported (backpacks fit into a plastic bag to avoid getting wet). If on the river we have turbulent current, then in this case it is advisable to refuse to pass a water barrier, since such a river can be dangerous.

Our next lesson will be about overcoming water obstacles. This may come in handy at the most unexpected moment. Let me give you a vivid example from personal experience.

We went to the forest for berries. Not far, about 5-6 km. from the nearest village. On two cars UAZ-31519 (mine) and UAZ-452 (friend). In the process of driving along the “wolf road”, we crossed a stream 50 centimeters wide and ankle-deep. We arrived at the place, set up camp, had breakfast, set off to collect the gifts of the forest. Toward evening it suddenly began to rain. Moreover, it was difficult to call it rain - drizzle, heavy fog. Declined. The rain continued to fall. In the morning, returning back, we saw in front of us .... Yes, as you may have guessed - a turbulent stream 4 - 5 meters wide and about a meter deep. And it kept raining. Looking ahead, I will say that the creek was crossed by both cars for several minutes without any loss. But… We were prepared and had a lot of experience. And what impression will this seething stream make on a beginner or an inexperienced jeep?! In addition to convulsive forcing attempts, we are very likely to get a drowned car. By the way, none of our cars was equipped with snorkels and had no special training.

Well, you presented the picture. We start forcing. The first is intelligence. It is advisable to have high boots (bogs) for this, or, which is generally ideal, waterproof semi-overalls (the so-called "chemical protection"). Why so serious? Yes, because sometimes it is necessary to wander in the spring, icy waters to the waist to find some loophole for the jeep. If you come back and remember the bottom topography, it's one thing. When you storm an unknown place, it's different. We take in hand the rope with which your friend will insure you. If it so happened that you are alone, or your fellow travelers have no strength (women, children) - tie a rope to the car. This is a safety measure in case of strong currents, convulsions, pits, etc. If the current is severe, tie yourself with a rope. Carefully probe the bottom with your feet. Stones, pebbles? Fine. It remains only to choose a trajectory without boulders, so as not to damage the suspension and engine. Sand? Worse, but not so critical - we feel the maximum firmament. Silt, clay, organic carpet? It's already much worse.

I will not describe the first two options - it is understandable and so, without prompts. I will describe how to act in the most difficult situation - a shifting, unstable day. We hook the cable to the car in advance, wind it up and throw it on the roof or hood - we fix it, in extreme cases - we throw it through the window into the passenger compartment. It's great if you have two cables - you can fasten them at once both in front and behind! It's great if you have a winch! Determine the anchor (a boulder, a tree, sticking out strong snags, poles, etc.) and unwind the winch cable in advance to a length reaching the anchor, or to the maximum length if the anchor is too far. Wind up the rope and secure it in an easily accessible place. Before driving, close all windows and vents - excess water we don't need anything. We remove all things from the floor of the cabin, place them as high as possible. If there is a heater, we remove it, or simply roll it tightly.

If, as in the UAZ-31519, the fan has a belt drive (it spins from the engine), then remove the belt or completely loosen the tension. There are several reasons. Firstly, a rotating fan will flood everything around (read - the engine) with water. Secondly, once in the water high revs fan blades (due to the positive angle of attack and water resistance) can bend forward, winding the radiator honeycombs and the radiator itself. In the latter, I, of course, exaggerate, but I hope you understand the danger.

Whether or not to expel your passengers is up to you, at your own peril and risk, depending on the uniform, age, and the degree of danger of the water barrier. It is possible to cross a calm stream all together ... But it is very risky to force a roaring rain stream with children in the cabin. It all depends on the situation, make a decision according to the circumstances.
Let's go. The first thing to understand and remember by heart is that we drive slowly, but evenly, at about the same speed. If you have a UAZ, close the radiator shutters.

It is strictly forbidden to fly into the water with acceleration! In addition to the fact that you can get water hammer in the radiator, the car will behave like a leaky float. The jeep will first hit the water, losing some of its speed. The rear wheels hang out and lose traction, the car starts to turn. A wave of water will fill the engine compartment, fill the candles and the variator, possibly reaching the carburetor, and, if there is no snorkel, the air intake. Then the car will suddenly pop up, the wheels will lose the ground and it will be carried to a deeper place. There, starting to sink, the car is guaranteed to stand up forever.

Overflows are not allowed. As soon as you see a wave in front of the car - adjust the speed, try to catch up with it (or, conversely, so that it catches up with you). The reason for this is simple - when the wave goes in front of the car in accordance with the graphic sinusoid, the water level in the engine compartment is MINIMUM!

Stops are NOT ALLOWED. Especially if the bottom is sandy or muddy! The reason is simple - a standing car is quickly washed away by the current into the sand, falling lower and lower.

If suddenly you feel that the car is about to get stuck and the depth becomes much greater than the calculated one, do not panic. Engage reverse very quickly and begin to move backward along your path. Attention! DO NOT allow SLIP when starting!

At the same time, take into account such a thing that people say: Fear has big eyes! Namely, when moving forward, you collect water in front of you and the wave, naturally going in front of you, visually raises the water level!

Next danger. In a strong current, the car can turn around or drag sideways. Get ready for it! In this case, you must immediately open all the doors wide open. The cabin will fill with water and the car will anchor in place. If the engine does not stall, proceed carefully. The salon, of course, will get wet, but this is the lesser of evils. After all, "auto-floaters" in most cases, the water flow simply Flips.

When submerged in water, get ready for a sudden release of a cloud of steam! Don't be scared, it's normal.

If the engine suddenly stalled and you understand that it stalled through your fault (for example, due to careless manipulation of the controls), try to start it right away. If the engine "grabbed" - increase the speed smoothly and immediately continue moving. If the engine does not start after two attempts - do not continue further - you are out of luck. You will have to extract the car with someone's help!

On the shore you can try to revive the engine. On gasoline - open the variator cover, dry it. We unscrew all the candles, drive the engine with a starter to expel water from the cylinders. Attention! Do not forget to short the high-voltage wires to ground, otherwise there is a risk of burning electrical equipment. By removing the coarse filter (usually located near the tank), we look at the presence of water. We wipe everything, dry it, screw it in and try to start it. In most cases, the engine starts without any problems.

Diesel is a little more difficult. If the crankshaft rotates with difficulty, we probably received a water hammer in the cylinders and bent the connecting rods. A tug or tow truck is already needed here and a very serious repair is ahead.

According to the statistics of hardened off-roaders, in the vast majority of cars they cannot overcome the ford and get stuck tightly not because of technical problems or difficult terrain of the day, but because of elementary crew mistakes.

Finally, a few tips just in case. If you understand that crossing the fords may not be a rare occurrence, you just need to equip your car. Despite the formidability of the event, it is simple and inexpensive. Necessary activities:
- Install the snorkel (removed air intake).
- In addition, we isolate the wiring. Electrical tape will not work, it is advisable to tighten it in a special mastic. The waterproofing of the wires is not critical, especially if the wiring is intact and not old (without transverse microcracks).
- We bring under the hood the ventilation tubes of bridges, gearboxes, "razdatki" (and other nodes that have breathers - depending on the brand of car). Maybe this will be a discovery for you, but the gearbox or the rear axle have so-called "breathers" - a mechanical bypass device for connecting the internal volume with the atmosphere. The purpose of breathers is to relieve or add internal pressure so that seals and gaskets do not squeeze out. During operation of the unit, the oil in it heats up and expands. If, say, the gearbox is made absolutely tight, the expanding oil will look for a way out. And the exit is in weak spot which are seals. The reverse process also occurs - when immersed in water, the oil cools sharply and a negative pressure is created in the unit. The breather "sucks in" air to equalize the pressure. And when immersed in water, the water will be “sucked in”. I will not explain to you about the consequences of finding water inside the unit, this is understandable to any sane person.

I will devote a separate article to the above topics with illustrations using the UAZ as an example. The design on other vehicles is fundamentally similar.
I wish you good luck and successful assaults on water barriers!

During the movement through the territory controlled by the enemy, rivers, tributaries, streams, channels of irrigation systems, etc. water barriers, which, quite likely, will have to be overcome on the move, without prior reconnaissance of these obstacles and careful preparation, without having specially designed means for this, in any weather, day and night.

During the movement through the territory controlled by the enemy, rivers, tributaries, streams, canals of irrigation systems, other water barriers will be encountered on the way of the group, which, most likely, will have to be overcome on the move, without preliminary reconnaissance of these obstacles and thorough preparation, without having specially funds intended for this, in any weather, day and night. Therefore, in our difficult time, it is useful to know how to short time and, in compliance with security measures, overcome water obstacles encountered on the way, how to equip the simplest crossing facilities using improvised materials, learn to evaluate the obstacles encountered on the way and choose the most appropriate ways to overcome them.

River crossings are among the most dangerous obstacles. Therefore, before forcing water barriers, it is necessary to comprehensively assess the possible difficulties that may arise when crossing unfamiliar rivers, take into account the number of people in the group, their physical fitness, the experience of the elder and other people in crossing.

Plain rivers are distinguished by a wide channel, a slow calm current, a soft or muddy bottom, often of great depth, mountain rivers - fast current, water level changing during the day, low temperature. The bottom of the mountain rivers is hard, rocky, the longitudinal profile is stepped, with rapids and waterfalls, in the upper reaches the current is swift, uneven.

Seasonal floods and bad weather can complicate the crossing. During torrential rains or shortly thereafter, river levels may rise. IN mountain rivers the water level is lowest before dawn and highest in the evening. This is due to the melting of snow and ice in the mountains. But in the middle and lower reaches of large rivers, the daily flood is late.

The seasonal water level in mountain and lowland rivers differs sharply. In the driest and hottest time of the year, when the lowland rivers become shallow, the high water is at its height on the mountain ones. This must be taken into account when developing an action plan and timetable.

Choice of crossing site. To ensure safety, it is important to be able to choose the right place for the crossing. Circumstances do not always allow the group to explore the water line in advance and choose a suitable place for the crossing. A topographical map helps to facilitate this task. It can be used to determine the direction and speed of the river, its width and depth, banks, fords. Unfortunately, such detailed information only found on military maps. On ordinary, commercially available, there are no such details. Given that military topographic maps at a scale of 1:200000 (1 cm 2 km) have been declassified and chipboard, try to have one.

Approximately determine the speed of the river can be in a simple way. To do this, they throw a piece of wood into the river and mark the distance that it will swim in one second.

By determining the direction and speed of the river, its width, you can find the amount of possible drift when crossing by swimming or using improvised means. To do this, the figure 2.5 is multiplied by the speed of the current (m / s), the result is multiplied by the width of the river (m). This will be the amount of drift. Having estimated how many meters people will be carried downstream, you need to choose the most suitable landing area on the opposite bank.

When choosing a crossing site, not only the speed of the current and the width of the channel are taken into account, but also the depth of the river, the availability of places for organizing insurance, monitoring and managing the crossing. In addition, the nature of the bottom and the stones rolling along it are taken into account, which usually make themselves felt with dull blows on the bottom.

When crossing a stormy river downstream, it is advisable to organize a post to intercept people in case they fall into the water and are carried away by the current. The post is set at the point to which the person who has fallen into the water should be carried out. This place is determined by a branch thrown into the water from the place of a possible breakdown. You can also throw a log, chips into the water. If they are carried on snags, whirlpools or sharp stones, the place for the crossing is unsuitable.

It is also necessary to check the place for the safety post. People on it should be safe themselves and be able to provide assistance. The belay post must be located in such a place that the rope does not cross dangerous places or obstacles. It is desirable that there is a tree or rock nearby that could be used to make a rope.

At the end of the rescue rope, a float is tied. With one hand, they take half or a third of the skein, and with the other, free, they throw the rest of the rope to the rescued (previously carefully laid to avoid tangling during the throw). At the same time, the end of 3.5-4 meters long is left untwisted.

The rope must be thrown to the place where the current carries the one who has fallen off at the crossing - downstream in front of the one who has fallen into the water.

The rescuer pulling the casualty should secure the rope to a rock or tree to make it easier to hold the person when he grabs the rope.

A person who has fallen into the water must know the location of the safety post and, in anticipation of a thrown rope, must turn around face downstream. Grasping the rope, the rescued person must be ready for a jerk and strong opposition to the current. The rescue line must be held firmly, but without wrapping the rope around the hand. The victim should approach the shore, sorting through the rope with his hands, until he reaches shallow water. After that, the rope is used to keep on one's feet during the landfall.

For the crossing, it is necessary to look for the safest areas. At the same time, sometimes you have to decide where it is better to cross: where it is safer, but there is a high probability of being captured by the enemy, or where there is no enemy, but the crossing itself will be more dangerous. In all cases, common sense and practicality are needed. It is not a bad idea to make an analysis and decide where there will be less possible losses.

The approaches to the river and the place of exit to the opposite bank should provide the maximum secrecy of the group so that it can prepare for the crossing and put itself in proper readiness after the crossing. It is necessary to look for a place so that the river bank from which the crossing will go is higher than the opposite, this will allow better control of the surrounding area.

If time and situation allow, then for reconnaissance of the other shore, where the group's path lies, it is advisable to cross to one person and only at his signal the others begin to cross.

In all cases, when crossing water barriers, it is necessary to keep weapons and ammunition in combat readiness, and clothes and shoes, if possible, dry.

Crossing wade. The site for the crossing should be sought where there is shallow water, since in these places the soil of the bottom and banks is always denser. The fords, which the locals systematically use, are easy to identify by the entrance of the road or path into the water and its continuation on the opposite bank. Places suitable for fording can be identified by the following features:

Visible shallows with clear water;

Places with sloping banks, where the river expands and forms spills;

Small ripples on the surface of the water with a weak current;

Water swings.

Swampy rivers, the channels of which are overgrown with reeds, sedges, and algae, in most cases are of little use for fording due to the high melting and viscosity of the bottom.

Before fording a river, especially in places that have already been used by troops or local residents, it is imperative to check whether the ford is mined, to determine whether it is under enemy observation.

The depth of the river and the condition of the bottom soil are determined by a pole. The pole enters the muddy soil easily, in the clay or sandy - with difficulty. When determining the depth of the ford, along with the layer of water, one should also take into account the layer of silt to solid ground.

The fordability of the river depends on the depth and speed of the current. So, at a current speed of 1 m / s, it is quite safe and without insurance to cross a river 1 meter deep, at a speed of 2 m / s, a depth of 0.6-0.8 meters is safe. The shallow stony bottom facilitates the crossing.

When choosing a place for a ford, you need to take into account that it is better to cross the river at an angle of 40-45 "downstream, especially when high speed flow. Never try to cross a river in close proximity to a waterfall. The stream must be crossed where there is convenient shallow water or a sandy spit on the opposite bank.

It is best to cross the mountain rivers in the morning, as in the middle of the day and especially in the evening, the melting of glaciers intensifies and the water level rises.

On small rivers, where the depth is not great - up to the knees, and the speed of the current does not impede movement, it is possible to cross without insurance and railings, but before that it is necessary to explore the path. Reconnaissance is carried out by the "wall" or line method.

For the crossing to the scout team, you should appoint the highest and strong people. The strongest of them gets upstream. It will experience the most flow pressure. The other 2-3 participants stand next to him in one line along the direction of the stream, put their hands on each other's shoulders, holding the shoulder straps of the back packs, and move forward with small steps.

No less reliable is the "Tajik" method. Four or six people, embracing the waist or shoulders, form a circle and, trying to coordinate their movements, walk slowly so that everyone can find the most reliable places for legs.

On more difficult places, the insurance of the first person going first is required. He is insured with the main and auxiliary ropes, the ends of which are tied on his back.

In this position, it is more convenient to walk, and it is easier to swim when carried by the current. When pulling it to the shore, a person floats on his back, and the water does not flood his face.

The one carried down by the current is kept on the main rope, while at the same time pulling the auxiliary one to the shore. Therefore, belayers with an auxiliary rope are located on the shore downstream from the main rope.

In the event of a breakdown, the crossing sometimes has to run along the shore, since the tightly stretched main rope can make it difficult to stay above the water. At the same time, the coordination of the actions of the belayers with the main and auxiliary ropes is very important. While the former make it possible for the crossing current to swim, the latter must pull it towards the shore.

On mountain rivers, you should cross in boots so as not to injure your legs. For stability, they use a strong pole, which rests on the bottom from the side of the current. Putting their foot down, they feel the bottom and look for a reliable support. After the first one has crossed, the railings are pulled up and the rest cross over.

Railing guidance. Even in cases where there is masonry across the river, which is used by local residents, or a reliable trunk of a fallen tree itself formed a bridge, it is necessary to build a railing. If the river is not wide, with a more or less calm course and downstream there is clearly no dangerous places(waterfalls, rapids, sharp stones, etc.), railings can be made from a pole, which two people each hold on their own bank. Walking along the masonry is insured with a rope from the shore.

Rope railings are built to wade across the stones, along the log to the other side.

The railing must be taut, as a loose rope can be more dangerous than if it were not there at all. Therefore, both ends of the rope are tied to supports. The best way trees on both banks.

If the tree is thin, the same end of the rope is tied to another tree, bush or support driven into the ground and littered with stones. A large shrub can also be used for support; the rope should be tied at its very root and secured in the same way as with thin trees. Rocky ledges, large boulders, stakes driven into the ground or poles littered with stones are quite reliable. The reliability of the railing is checked by the one who goes first with insurance from the shore.

The end of the rope, fixed on the shore, from which the crossing begins, must be tied on a support with a knot that can be easily untied after the crossing is completed. If you pull hard on the rope that is tied to the free end of the knot, the knot will easily unravel. It remains to pull the rope out of the water.

Crossing over protruding stones held on the rifts of shallow mountain streams and rivers. If in separate places river stones are located far away, you can make artificial islands. For self-insurance, there should be a pole in the hands, with which the bottom is probed, the density of the stones, their mobility, and additional support is created.

When crossing rocks across dangerous rivers, insurance is always required.

Hinged ferry, This type of crossing is the most difficult, therefore it is used only when there is no other way out. In the absence of a sufficient number of ropes, hanging crossings are not possible. The choice of a crossing point is determined by the following requirements:

The width of the river should be less than the length of the main (unconnected) ropes by 8 - 10 meters;

- both banks must be raised above

water, taking into account the inevitable sagging of the rope;

The shore from which the crossing is carried out must be higher than the opposite, in addition, there must be trees, a rock or protruding stones on it, for which a rope can be tied.

When the place is chosen, you need to fix the rope on the opposite bank. This is done in different ways: you can throw a double rope with small stones or sticks tied to its middle in the hope that they will overwhelm the trees. If a ford is found, the strongest of the group on a thorough belay or swim on improvised means also goes to the opposite bank with insurance, where he fastens the two main ropes to a tree, a protruding rock or clogged hooks. The rest pull the ropes tight and fasten them.

With the help of an auxiliary rope, fixed in the middle, stacks are transported to the other side, then people. Those who cross with their heads in the direction of the crossing are located so that they can pull themselves up with their hands to the shore when the rope sags.

The middle of the auxiliary rope is attached to the chest harness on the back to help pull up to the opposite shore and return the chest harness and arbor for use by the next person, the trailing one fixes the ropes so that after crossing it, they can be removed from the opposite bank.

Crossing the masonry the most convenient and safe, especially in the cold season, with great depth and strength of the stream, stones rolling along the bottom. Usually masonry is found in forests and is used local residents. This is a fallen tree trunk or several fastened poles fixed on the banks. Such masonry is unstable, often carried away by water after floods, so they often have to be done again. Sometimes it is possible to find a washed-out section of the coast with a tree strongly leaning towards the other coast. Such a tree can be felled and used as a bridge. Only first you need to cut off the branches and branches that will interfere with the crossing. So that the tree does not fall prematurely, but lies in the right place, it is secured with ropes. In addition, these ropes will serve as a railing for the first person to cross. In many places in the mountains and taiga along the banks of the rivers there are fallen trees. After making sure that the tree trunk is suitable for crossing and lifting it according to the strength of the group, they begin to work. First of all, it is cleared of branches and branches. To prevent the trunk from being slippery, especially during rain, its surface is covered with notches.

To prepare the masonry, an emphasis is first made of stones or a hole is torn off. Then a rope is tied to the thinner end of the trunk in its middle part, and the trunk is placed parallel to the shore. The thick part of the trunk is placed near the stop, and two small groups are held by the ends of the ropes. After that, on command, both groups begin to pull the stretch marks and raise the trunk. For safety reasons, the senior group must ensure that there are no people within the radius of the trunk, The trunk is raised at an angle of 40-45 degrees to the ground, It is undesirable to increase the angle, since the log may fall, and when smaller angle it will be difficult to hold and direct in the right direction.

Then, without lowering the trunk, they slowly lead it towards the other bank and, at the command of the elder, slowly lower it. If you just drop it, it may break. After the log has laid its end on the other side, its stability is checked, if necessary, stones are placed or stakes are hammered. Then both ends of the rope are pulled to the limit, turning it into a railing for the first participant, who comes with insurance and after the crossing prepares already high-quality railings.

The top of the trunk can be rafted to the opposite bank using the force of the current. This method is also possible for a small group.

To do this, the trunk is laid parallel to the shore, securely strengthening the butt in the nest. Then the rope is tied in the middle to the thin end of the trunk. After that, the trunk is gradually pushed into the river, holding the butt until it is picked up by the current. When the end of the trunk begins to approach the opposite bank, they try to lift it a little higher and push it ashore, pulling both extensions.

The barrel must not be flooded with water. If, during the crossing of the first person, the log sagged and touched the water or went into the water, he, having crossed and tied a rope for the railing to the support, should try to move the end of the trunk higher.

In order not to fall into the water, you need to walk along the masonry calmly, on one log there should not be two or more crossing at the same time.

Crossing swim. To overcome the river by swimming, you should choose the narrowest sections of the channel or cross in places where there are islands or shallows where you can relax.

When crossing by swimming in clothes, you need to remember that the swimmer's weight increases due to

water soaking into clothes and shoes. To prevent excessive weight gain, unbutton the sleeves and collar, turn pockets inside out, and remove shoes.

Such a raft is great for transporting things, but for people it is too small. Holding on to the raft with one hand, they push it in front of them and so they cross to the other side. If the current is fast, then it is advisable to tie the raft with a rope to your hand so that it is not carried away. To covertly overcome a water barrier, you can use a tree trunk. They clasp it with one hand and swim, pushing off with their feet and raking with the other hand.

For camouflage, you can use floating boxes or a self-made artificial island. These methods are good for a small group of 2-3 people, as more of these items on the water can cause suspicion and shooting at them.
