Great campspot at the shores of the Colorado River. Elves Chasm with fresh water from Royal Arch Creek is around 1.3 miles (one way) down the river. You can also filter water from the Colorado, but since has a lot of sediments, it could easily clog your filter if you don't give it the time to settle.
To camp here, you need a backcountry permit for BR9, Garnet, At Large.
