True mountain mahogany or curl-leaf mountain mahogany. The posts above are correct, it is a mule deer staple, especially towards late summer, fall, and through the winter. That stuff looks pretty healthy, some of the mountain mahogany on the winter range around Baggs Wyoming looks like those little sculpted trees you see in Japanese gardens because it's been hit so hard year after year after year.
This hunter loves it, where you find healthy patches in the country we hunt, you will find quality deer habitat. Some other plants that are good for the serious mule deer hunter to know are antelope bitterbrush and serviceberry.
