Swasey Limestone (Middle Cambrian), House Range, western Utah. Looking northwest over Tule Valley. The views are hazy due to smoke from the California wildfires several hundred miles west!

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.

Just off the Shingle Pass road, looking east toward Patterson Pass. The Cambrian Pole Canyon Limestone forms the prominent white cliffs on either side of the pass.
