I was able to hunt in the woods last winter, here in PA., when there wasn't too much snow on the ground. I think it depends on the individual area, and how much water is retained in the soil you're trying to hunt.
Already, just this December, I've tried to hunt in areas that I could dig in, and areas where the ground was frozen like concrete.
I noticed that I could still dig in the wooded areas on hillsides or hilltops, cause I guess they're areas that the moisture can actually flow out of on warmer days. But lower lying areas, that hold the water in the soil more, were frozen rock solid. You'd break your foot before you could dig a hole.
Oh, another stupid thing I've tried before, was carrying gallon jugs of HOT water in the car with me, and if I got a good signal, I'd pour hot water where I was gonna dig a plug. Of course I'd REALLY have to LIKE the signal before I wasted the hot water!
TRUST ME, this was a waste of time! It doesn't work like I hoped.
Of course if there's just too much snow on the ground, you wont get any depth.
And now we're supposed to be getting ANOTHER snow storm here tonight.
