Summary Author: Rick Scott
Shown 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. Photo taken on October 3, 2015.
