Death Valley National Park
Golden Canyon Trail
It would be possible to hike to Zabriskie's Point (5 miles), but I did not have a map so I opted to drive there instead. It was hard to discern the main trail from the drainage forks.
Trailhead: 30 mile drive south from Ubehebe Crater, high clearance vehicle needed but not 4WD
The southeast corner of the playa has the best rock displays. Continue past the "Grandstand" to the south end and hike out to the mountains where the rocks are falling down onto the lake bed. Rocks with GPS units were placed out on the playa to solve the mystery of how the rocks move, video can be found here.
