Time for those red-blue glasses again!
And Wow! Look at that depth of field! |

Normal fault in the Fort Hays member of the Cretaceous Niobrara Formation, south of Stockton, Kansas. These chalk beds were originally deposited in the shallow Western Interior Seaway about 80 million years ago. The thick beds of the Fort Hays member are extensively bioturbated. Faulting is post-Cretaceous and pre-Quaternary. |

180+ degree panorama along 12 Road in southern Rooks County, Kansas. The distant cliff formed by the cutbank of a small stream exposes the rarely seen contact between the Fort Hays and Smoky Hill members of the Upper Cretaceous Niobrara Chalk. The Fort Hays member is characterized by thick bioturbated chalk beds whereas the overlying Smoky Hill chalk is thinly bedded and rarely exposed in extensive outcrops. |

Castle Rock is an erosional remnant of Cretaceous Smoky Hill Chalk in southeastern Gove County, Kansas. Historically it was an important landmark on the Butterfield Overland Trail.

Central section of the long roadcut on KS-183 north of the Saline River Valley. This cut exposes an almost complete section through the Fort Hays Limestone member of the Cretaceous Niobrara Formation. These chalk beds were laid down at the bottom of the shallow tropical Western Interior Seaway. The thick beds of the Fort Hays member are extensively bioturbated and reworked storm deposits. Individual beds are traceable for many miles. Shaly interbeds reflect deeper water depositional conditions. |

Long roadcut throught the Fort Hays Limestone (chalk) on KS-183 just south of Stockton, Kansas. The city of Stockton can be seen in the distance on the right side of the image. A detail of this image is at http://www.gigapan.org/viewGigapan.php?id=2859 . Another detail of the fault near the top of this section is at http://www.gigapan.org/viewGigapan.php?id=2166 . |

Just up the hill from http://www.gigapan.org/viewGigapan.php?id=1955 .
It was a very cold morning. I was glad to get back in the car out out the wind while the robot did its thing. :-) |
