Limestone cliffs

27 Nov 2018 3 4 507
Just west of Swasey Peak in the House Range, western Utah. The prominent cliff at the right is formed by the Swasey Limestone; the lower one left of center is the lower part of the Dome Limestone. All the units are Middle Cambrian in age. We're in the so-called Cordilleran Miogeosyncline here, a thick sequence of sedimentary rocks now interpreted to be the continental margin at that time, ca. 500 million years ago. The views should be _lots_ clearer--it's murky due to smoke from the California wildfires several hundred miles west! The Inset shows a slightly different view.
