Outdoor Knowledge Lecture: How to help themselves unexpectedly lost the wild

Often, people get lost because of their location can not be known with certainty with a number of factors, including natural or the other, linked together and used as a guide. At the same time , also because of the lack of observation and more systematic scheduled to leave and return to the base ( such as trails, roads, rivers , power lines , streams or lakes, etc. ) hiker knowledge . When traveling just put a particular point ( such as tents, hunting lodge , cabins, boats , cars, etc. ) keep in mind , these are often caused people sometimes get lost is part of the reason .

The content here is to introduce some direct , relying on walking , non-professional approach. For the survival of these methods to determine the direction or stray easier , faster, and it will they bring to the nearest place from your destination , using these methods , even if you do not have a compass , maps, astronomy, geography does not have the expertise , you can also in which to determine their position.

       How to avoid getting lost

Unless you select a fixed target as a guide , otherwise , people will be lost , because the bend in the road , dense forest , distance will cover destination. To do this , you must remember the following method to avoid getting lost :

You must always observant surrounding terrain to determine the direction . Before you leave your tent , car, single-plank bridge , boats and other objects prior to careful observation of the surrounding terrain, visual look as far as possible in this region , identified about a variety of fixed target wizard , such as mountains, cliffs, temples, large trees.

Before departure you want to highlight those goals around the camps have a clear memory , so that when you return , can use these goals as our guide .

When you leave a road , a creek , a footpath , a river, a mountain or a temple , remember which side is left , use these as the basic line .

Remember that when you come back with the number of streams through the journey after a number of peaks , the number of fork road. I walked down the road to draw a circuit diagram .

Retrolabyrinthine how to do

If you find yourself in an unfamiliar area , and difficult to find the way back to their camp , this time would not say he lost his way , at least for now is not what you might be within a few minutes of confusion .

If you suspect himself astray, should immediately stop and try to estimate the situation and blindly continue to move forward , the situation would be even worse . Do not panic , sit down and relax. Do some deep breathing , smoke a cigarette , chewing gum pieces , carefully recall through houses, streams or other geographical features , in pursuit of what they have gone through the route . Quietly sit a few minutes.

When the hiker just found him difficult to orient yourself when , under normal circumstances he did not go far, not find one. The trouble is that most of those who continue to blindly ahead lost in the forest Luanzuan scurrying to make their situation worse , some of the stray or even completely out of the search area ranges.

There are maps , then first check out the legend , to see what each symbol represents , and find out about their foothold on the map which district . Look around there is no match with the geographical characteristics of geographical indications . Before getting lost on the map to find the location , and then recall through houses, streams or other geographical features , in pursuit of what they have gone through the route .

See a map of contour lines, in order to understand the surrounding terrain. Contour representation gentle mountains far away from each other , there is no contour lines indicate broad plains or ridges, wound into a fingerprint-like contours are mostly spur or valley . According to the scale of the map , for example , a scale of 1:50000 , it means that 1 cm on the map represents the actual length of 50000 cm ( 0.5 km ) , with a small ruler calculate their distance to the target object . If no pen and paper , finger rough estimate distances , in general , adult index finger off from the fingertips to a savings of 2.5 cm long .

Rotate the map , so that the subject of the map and it represents geographic features in the same direction , and then click to select a certain direction or walk the road where people smoke .

From the look on a map the route before the trip , there is no obstacle , such as cliffs , wide rivers . If you have , you should find another route to go around . Use the map to the same geographical features and the field as a guide . Edge on both sides before the line while you watch the scene , see the map estimate how far away .

Storm lost self-help

If subsistence bags ( can accommodate the whole person waterproof plastic bags ) , or other living equipment , can be left in place waiting for the storm , if there is no living Bag equipment , must remain in place , you should leave quickly .

As with maps, see if there is a danger zone . For example, dense contour lines indicate a steep cliff , you should take a detour.

Streams flowing down the route display , but not close to the streams and the line, because the power of the mountain river water erosion is very strong, very steep riverbank . Therefore, we should follow the sound of water along streams down the mountain.

There is no down time watch farmhouse or other sheltered places, trails can be found nearby usually hiding.

Do not approached with long light green , spike-like grass depressions , there is likely to be swamp.

Night lost self-help

If the moon , you can see the surrounding environment , should try to roads or farmhouse .

If living in the dark mountains , can not see the surrounding environment , do not continue to walk , you should find a hiding place , such as a wall or rock leeward side.

If living with the bags, which should be drilling . Several people huddled can protect warmth. Thus, even without vitamin bags can survive cold night . Warmest middle position , so you should from time to time reciprocal translocation .

Snow lost self-help

The white snow reflects the same color as the sky , the terrain becomes blurred ; horizon , height, depth and shadow completely faded . Mountain climber and explorer called this phenomenon " whiteout ."

At this point , it is best to stop and wait for whiteout disappear. Such as waiting for when the storm should be hollowed out snow pit , or expanded portion of the snow pit roots , and then go hide .

If subsistence bag, mat leaves behind hay , to separate the cold ground , and then go hide .

As much as possible to wear layers of clothes , the outermost layer of clothing if there are any buttons or zippers , first fastened , one way or another , and then sets in the upper body .

Within the clothes cross arms, palms clip in the armpit , in order to maintain warmth.

If you must continue to move forward , you can use the map and compass for direction . While walking forward throwing snowballs , snowball attention falls where and how to scroll to detect slope obliquely . If the snowball one go without a trace , it could be in front of the cliff .

Mist lost self-help

Pulled out a map and go in the same direction with the compass , and then decide which direction to go .

Follow the compass requires, looked towards his direction to go , select an easily identifiable targets, such as rocks, trees, fern leaves . Walked over to the target , and then follow the compass looking in front of another target .

This method is used continuously until the lock out of the fog .

If there is no map or compass, should remain in place , waiting for the fog to dissipate

Map wonderful knowledge without direction method

Even without a map and compass , it is possible to find the route leading to a safe place .

First, consider the possibility of return just traveled road .

Impossible to go back , you observe the environment . As will be seen roads or road connecting things, such as housing , utility poles , etc., should be towards it .

If the approximate geographic features from around the inferred where I was on the road toward the closest , paths , railways , rivers and so on. Edge forward while you watch street scene , estimate how far away their own .

With the forward line perpendicular roads, rivers and other targets is the best choice , because even slightly deviated from the original advances route can also be found .

Roads, power lines and phone lines right way was regular inspections , you will encounter people do not have to wait long , they will help you find the way to go .

If not find a reliable geographical features can be used to distinguish the direction of the sun to decide which direction to go .

Noon in the northern hemisphere the sun at the zenith by the south , the southern hemisphere to the north in the zenith .

If the sun is blocked by clouds or take a small nail file dao blade edge heel in plastic like a credit card or thumb nails shiny plane, from the plane to find faint shadow. Sun and shadow in the opposite direction .

If the pointer watch and has been calibrated to identify the direction local time the following method :

The watch is flat , the hour hand pointing to the sun , and imagine a line to the angle between the hour hand and 12:00 split in two . For example , if it is 16:00 , bisector will pass 2:00 . This bisector will point due south in the northern hemisphere , in the southern hemisphere is pointing due north .

Thick dense clouds see the sun , can be observed on tree trunks or rocks moss . Moss often grow in shade , in the northern hemisphere , north or northeast moss that side more, in the southern hemisphere , the south or southeast moss that side more . However, with moss speculated direction is not accurate, so if the sun through the clouds , you should use the sun to determine the orientation .

If required to stay in place for some time , you can erect a measuring stick on the flat direction . Every hour or so , the top of the shade on a stick to make a mark , the mark in a line, it will point to the east and west side .
