A Modern Wonder from Ancient Dunes: The Iconic Navajo Sandstone, Part 1

The majestic and iconic Navajo Sandstone has become ubiquitous in scenes from the Colorado Plateau. Margie Chan, Professor Emeritus at the University of Utah, has studied the Navajo Sandstone her entire career and we discuss the deposition and unique features of this Jurassic wind-blown sand. This ancient desert extended across much of Utah, Arizona, and Nevada, and combined different geological structures including dunes, lake deposits, and springs. In this first of a 2-part series, we talk about the key role that groundwater plays in the sediment deformation and coloring. The next episode delves into the role of iron in the Navajo sandstone and its connection to Mars.
