What are the uses of rock crevices, caves, and disorderly rock tents

4. Stone crevices, caves, and disorderly hills
This is in extremely bad conditions, which means there is no place to camp at all. So I would like to ask, what is the purpose of a tent? First, of course, it is rainproof. If there is no rain, can we not camp? Then, second, it has a certain warmth effect. Alright, if your sleeping bag can meet the temperature requirements, why do we have to camp and sleep like this? Of course, sometimes there are insect infestations. It's not very serious, so let's endure it. If the weather conditions are also extremely bad, haha, you will encounter any unlucky thing, only use the last trick! Firstly, wrap the moisture-proof mat and sleeping bag around the inner tent, and of course, leave as much space as possible inside. Place clothes or other items on the top of the head to support the cloth on the head and facilitate breathing. Then, cover the outer tent on top, and a rainproof, warm, and insect proof nest will be built.
The above situations are just a starting point, I believe everyone has other methods. Of course, the most important thing is to make the plan as detailed as possible every time you travel. You should consider the water source, campsite, and team size carefully, think ahead of difficulties and accidents, and avoid starting to panic when situations arise in the end. Camping in harsh outdoor environments is quite complex, and it is necessary to adapt to the geographical environment and use it flexibly to ensure high-quality sleep and reserve physical strength for the next day's hiking.
