Mosaic Canyon is a short drive up a dusty road (I sound like I'm repeating myself. OK, all unpaved roads are dusty in Death Valley unless it's raining, then I would assume they would be impassible in many places, but then that's not happening all that often) from Stovepipe Wells. The canyon, repleate with rattlesnakes and loose rocks, is still a fairly easy hike and an interesting photo opportunity.
