A Capitol Day! (Capitol Reef that is)

Drove to Capitol Reef NP today.  The rocks are primarily Triassic and Jurassic that were bent into a monocline called the Waterpocket Fold.  Formations exposed in the park are, from oldest to youngest, Moenkopi Formation, Chinle Formation, Wingate Sandstone, Kayenta Formation, and Navajo Sandstone.  Cross-bedding is particularly prominent in the Wingate and Navajo.

Formations exposed from oldest (bottom) to youngest (top): Moenkopi, Chinle, Wingate.  The pyramid peak in the background is  Navajo.

After leaving Capitol Reef, I went to Arches NP to try and get a sunset photo of Delicate Arch.  No luck as the clouds closed in about an hour before sunset.

Tomorrow I'm heading to Canyonlands and Arches again.
