How to get there? A hiding place in a geothermal valley. (Rise of the Tomb Raider)
Can't get in there, and it's kind of impossible . Before a cache is a fence, and jump over nowhere .
maybe here is the answer ->

How much I remember, at that place are pumpkins (5-6 pieces) for the test... Think is the Apple or something like that... a Long time passed, just do not remember...

Well, for the pumpkins next to the rocks that are near the fence, must be a secret stash. If not, then it's probably in the tomb, which is located below the earth... In any case there can be get using Quick move in the Camp. The only map, as far as I remember correctly you can't go back using Camp, this is the first map in the beginning of the game. I couldn't get to 100% the game due to the fact that I missed one box at the beginning of the first card. And so all clambered everywhere.
If I am not mistaken, later it can be back in the story. Not all things are going right.
