It's a rough environment for trees, cold long winters and a constantly shifting, terribly rocky terrain -you can't dig a hole in this ground here. Your shovel hits a large rock, you remove the rock, then hit another rock. I tried a little gardening a while back, and it was a royal pain. When you take away the rocks, there's nothing left - very little soil to speak of for gardening purposes.
But they survive and enough thrive that there's a fair amount of timber here for the taking, as witnessed in the picture of cut logs in the previous post. The road you see in this middle frame is a lumber road.
