Found black leather duffel bag with 'Adventure awaits' patch near High Rockies trailhead containing books and a travel pillow.

I found a black leather duffel bag abandoned by the High Rockies trailhead while I was hiking. It looks brand new and has an unusual patch on the side that says 'Adventure awaits'. It was lying open, and I checked inside to ensure there was nothing sensitive or personal, but it only had a couple of books and a travel pillow. I would like to return it to its owner.
