Cross-bedding

This is the classic example of cross-bedding, that is sandstone composed of seashore ripples and sand dunes. The direction of the beds dipping indicates paleocurrents. See Wikipedia:Cross-bedding. These formations are prevalent in the Zion Canyon area of Souther Utah, one of my favorite places in the world. I love the patterns and the colors. You can't miss this hill if you drive from Mt. Carmel Junction to Zion.
