Although a few photos are a little difficult to call without closer inspection preferably in person. But, definitely not moose. Rubs are way too low. Some rubs are definitely deer and some may be elk. Elk and moose rub much earlier in the fall because they rut much earlier, and deer not until late October/November.

However, deer, elk and moose will rub the velvet off their antlers usually in August. Sometimes in early September also.

Track looks like a younger elk. Female is my call. Some trees in photos are Poplar (the nice smooth greenish bark) and some are balsam fir (the blister like bark). A few others are a little difficult to call without closer inspection. Most likely that balsam fir photo was up higher elevation, where balsam fir like to grow.

Hope that helps..
