I drove to Boone Colorado in July 1999 to see a geologic formation called "Tepee Buttes". These are the pictures I took.
A geologic feature called Tepee Buttes near Boone Colorado. The Roadside Geology of Colorado (Halka Chronic), page 67, describes Tepee buttes as "Congregations of marine shellfish, possibly living in patches of sea grass, built reef-like aggregates on the floor of the shallow Cretaceous sea. Today these limy aggregates, more resistant than the surrounding shale, form Tepee Buttes.".
To learn more about the Tepee-Buttes see: Tepee Buttes: Late Cretaceous Submarine Springs of El Paso and Pubelo County
I stopped at the B-24 museum on the way back from Boone, unfortunately I arrived too late to get in, but I still got some nice pictures.
The B-24 museum (also called the Fed E. Weisbrod Aircraft Museum) is located at the Pueblo Memorial Airport is open Monday - Friday, 9AM - 2PM. Admission is free. Unfortunately, I arrived after 3. I still got some nice picturers though from outside the fence.
