I was wondering the exact same thing. We hunt the general season in some fairly rugged country around 6000'. I was hiking up this one ridge and found a decent 4 point shed, i couldn't believe that I found that up there. That area gets hammered with snow, but it is on a fairly exposed south facing slope. One of the guys I hunt with also found a big 3 point shed about the same elevation but just a few small ridges to the east of where I found mine. I just can't believe they winter up there, those are some hardy deer.
