Description
Located in Nevada, an outcrop of Aztec Sandstone (Lower Jurassic) showing distorted eolian sand beds. What you see is the fossilized cores of old sand dunes laid down during the early Jurassic Period (180-190 million years ago,)
The sand slowly changed into sandstone. As subsurface water percolated through the sediments, depositing iron oxide and calcium carbonate in the pore spaces between the grains. These sandstone formations were slowly uplifted thousands of feet to their present elevation and exposed to weathering and erosion.
