Nice photo, wyominglostandfound.
Love that big tree on the left side. What a great forest to hike in. It'd be great to see more photos of your area.
I have never found antlers lying on the ground like that. After hunting season it's not uncommon to see deer carcasses, but they don't last long, the buzzards make incredibly fast work of them. I don't know what grabs the antlers around here but they must not wait long to get them.
