Outside the entrance to Capitol Reef National Park is this particular outcrop - the red layers are offset just to the left of the mesa at the right side of the pan (I'll snapshot it...). There's a nice description of the geology on a nearby plaque (not visible here....) |

Colloquially called 'the blues' because of the blue-grey color, these sedimentary rocks outcrop in a canyon along Rte 12 in southern Utah.
The blue-grey rocks are part of the Cretaceous Kaiparowits formation, which formed when large rivers deposited their sediment. The orange layers in the distance are made up of younger Claron Limestone - this is the same rock unit that appears in Bryce Canyon. |

That's the name given to this particular overlook along Rte. 12 in southern Utah. Large expanses of Navajo Sandstone make up the majority of the foreground rocks - these were once (millions of years ago) a vast expanse of sand dunes. The remnants of the dunes are found in structures called cross beds, where layers of sand from the dune meet layers of sand from the original surface at an angle. |

Another view of "the blues" in southern Utah, where blue-grey sedimentary rocks are exposed along Rte. 12.
These rocks were formed from sediments deposited by a river around 100 million years ago (Cretaceous period, Kaiparowits formation) |

A very curious roadcut. On the left side of the cut the Fort Hays Limestone depositionally overlies the Blue Hill Shale. On the west side of the cut Codell sandstone is exposed in the footwall of an eastward dipping fault. Slickensides on the fault surface suggest dip-slip offset. Thing is, where it does occur the Codell sandstone normally occurs depositionally between the Blue Hill and Fort Hays. Makes this a real head scratcher... |

The lighting conditions were not optimal, which is why the sky is so washed out. The good news is that they got better after this... |
