We have hunted the Monongahela National Forest three or four times and with talking with the locals when it snows hard it piles up in the hollows significantly. The highest mountain in the MNF is around 4800 feet and they get more than a little.
Tried to find the average snowfall for the area, but didn't have any success. Did see where hurricane Sandy in 2012 left around 33 inches in one storm and I'm sure there was more after that.
When it snows more than a little and then a rain follows, the steep hills become ice covered and are death traps for Deer. Same thing used to be fairly common in Pa years back.
He definitely puts his time in. He usually gets one in Pa and then heads to Ohio for ML. Can't remember when he hasn't been successful there in ages. Not Pa sized Bucks, but he is usually in and out with a Buck fairly quickly.
Of course you could trap out a pond, and if you keep shooting Does were they are few you can shoot them out also. We proved it. We control the game and if an area has few Deer, than common sense tells us if we want more in that area not to kill the few remaining. Hunt where they are and give where they are not time to rebound. But no, most are tied into a specific place and refuse to do so. End result is the rebound never will occur.
