best thing to do is run down hill and out of the mountains, flat out and deal with the consequences of what you find at the base of the mountain.
But don't feel badly towards the dev , now devs, as you just have to work out how to deal with it.
If you go into the mountains without good weapons and diet you will get killed.
I dont have a problem nor most other players so while I , in a friendly manner, feel your panic and wish you well , the raids are fantastic so you always have to keep your stamina up by advancing slowly, lots of rests, and have your weapons ready but on your back.
Also have a base at the foot of the mountain so you can recover your gear after you are killed.
remember if you have a base in the snow and ice and you havent placed antifreeze potions in your boxes, you wont be able to escape as you will be naked and freeze instantly if you race out
