Environmental interpretations of the Navajo Sandstone based upon modern textural studies were used, …The depositional environment can be characterized by it’s levels of oxygenation and energy. A high-energy environment is one in which the water is fast-moving and agitated, able to carry particles of large grain sizes; typically this occurs in shallow lakes & seas and in rivers, as well as deserts. A depositional environment is a natural or artificial layer of sedimentary material that covers an area and is created by the deposition of material from the atmosphere, water, or land.
