I have some wood available to me. I am very very tree savvy, meaning i can usually ID about any tree i come in contact with and if i cant i can usually find it on the net. unfortunately being winter no good leaves available but ican give you a description of what they did look like also a description of some of the fallen leaves. Im just plain stumped so name a few you think it might be and maybe it will give me that little extra kick in the pants that says "yeah you didnt think of that did you"
by the way, im in central montana other trees close by are ponderosa pines, quaken aspen, rocky mountain maple. hawthorn, russian olive
so the leaves are a round shape and toothed, but not aggressive teeth. they are about the size of a 50 cent piece, they dont seem to be in any particular order, not opposite and not consistent alternating pattern either. they remind me of a hazel leaf but they are a bit more round, smaller and not as thick and fleshy. looks like it might have had flowers, berries or seeds of some sort, but my treestand was right next to them and i didnt see any fruits, nuts or flowers during the fall. bark is smoother much like young maples or hazels, not scaly or flakey. no thorns and no nuts on the ground
what i know its not- black cherry, choke cherry, elms, hornbeams, hazels, maples, birches, hickories, oaks, hawthorne, olive, persimmon, dogwood, osage, mulberry
ok give me some more ideas. ...this is where some of you native westerns can come into play
