the elk will not move lower or shouldnt change habits at all based on a few inches of snow would need a few feet or more is my experience. Cow calling is still effective but more to stop the elk if they sppok a little but dont quite know what you are. Crunchy snow just sucks but I would move fast till I am within maybe 100 yards and then go really slow and then try to be even slower. I was making a lot of noise in the late season here and did some soft cow calls just to try and cover my noise and had a spike come in to about 40 yards( I missed!) So you might be able to get an elk to come check you out with some cow calls unless the area is heavily pressured and they have already heard every elk call out there for months. In that case best to just keep silent unless trying to stop one. Since we have such a long season I have not had too hunt the late archery a bunch but these things have worked for me when I have done it. So I am no expert but If you can cover a lot of ground and put on some stalks it is really a lot of fun. good luck and I still have my elk tag so I will be out there too come Dec 10 in Idaho.
