Christina watches a stream of sand flow down a slope at the Coral Pink Sand Dunes near the Arizona/Utah border.
The pedestal holding this boulder is about 6 feet tall. As the nearby cliff (not shown) would erode, large boulder would come tumbling down the slope and settle on the very erosive soil. The boulder would protect the soil directly beneath it from erosion as the surrounding soil was washed away by the fierce rain storms. We found this along the road near the Navajo Bridge.
