Post season is the best time to scout, snow or no snow. The deer trails are distinctive this time of year and the rubs and scrapes from the deer sign from the past fall are still easily visible.
As far as mapping the big woods, there are many different things I look for. I have that book that was mentioned "Mapping Trophy Bucks" and it does have some useful tidbits, but a lot of it is meant for farmland bluff country and doesn't apply as well to the big woods. I hunt two different types of big woods also, the plateau region, which sounds like where you are looking at, and the ridge and valley. Each has different features that affect deer movement. Remember that terrain features don't have to be extreme to affect deer movement. Even the most subtle benches and saddles influence deer movement if it is the easiest safe route of travel. I also find funnels to be highly effective, except where a lot of whitetail hunters are using open fields or CRP to funnel movement, my big woods funnels are typically created by either unpenetrable laurel or rock gardens. Neither of those are easily mapped, but I have found a few really good ones just wandering through the woods.
Clearcuts are great food sources and cover at the right age. Deer need food and cover to survive and thrive, so covering both their appeal is obvious. I have several good archery stands on clearcut edges. One thing I often see is other hunters place stands at the outside corner of a clear cut. Deer trails rarely use those outside corners unless driven by some other terrain feature. Inside corners, logging roads in the cut, and terrain features like benches and saddles influence deer travel in and out of the cut. Another thing to just be aware is that the DCNR fences most of their clearcuts for about 10-15 years and the PGC fences some as well. Those are obviously useless until the fences come down.
