First, is this a Spotted Hyena?
Second? I know he's partially out of view, but what is he doing? Is he scent marking?

It does look like a hyena. It looks like it's resting in the shade, and rolling over during its nap. Hyenas scent mark primarily by pasting a secretion from their anal gland onto grass stalks, so it looks a bit more intimate than this.
