Crossbedding

Crossbedding in Zion National Park
Photographs by Jimmie D. Agnew

Crossbedding occurs when deposits accumulate from wind or water that changes direction. In streams, crossbedding results when streams change course. For wind deposited sediments, sand accumulates at different angles when the predominant direction of the wind changes. In Zion National Park, evidence of the changing direction of the wind is preserved in these fossilized sand dunes. Various angles of deposition are evidence of wind's coming from different directions.
