How to unlock the The Old Trapper achievement in The Long Dark - Definitive Guide
Jeremiah will task you with getting medical supplies from the Carter Hydro Dam. You will find the key to the front gate in one of the trailers outside. Once inside make your way upstairs, you will see a locker which is all red but is locked. yoiu will find the key in a little side office. Once you have the medical supplies return to Jeremiah and the achievement will unlock.
For me, they were on the workbench outside of office on 2nd floor.
Story related can't be missed.
When you come out of the cave from Episode 1, you'll get a cutscene where Jeremiah is being attacked by the bear and you save him. After the cut scene you get a mission to go the the dam for med supplies and come back. The easiest way to do this is get out of the trappers cabin, and walk down the hill and go right with the mountains on your right until you see the train tracks. once on the track follow it left all the way to the end to get to the Dam, inside the dam loot everything as it has great loot and get the med supplies from the quest log. when you leave the Dam just follow the same route back the the cabin.
Note there are wolfs on the track especially in the dark! they can be scared off by a gun shot or throwing a flare at them.
