October  2015 Viewer's ChoiceShown above is an example of well developed cross-bedding in Navajo Sandstone near Lake Powell, Arizona. Navajo Sandstone is formed from ancient sand dunes that lithified over time. Cross-bedding is created through the migration of sand dunes. With cross-bedding, the inclined laminations are deposited at the same angle as the migrating face of the dune. This process was repeated several times in order to create the strata featured here.
