Tag Archive for: Book Cliffs


The Book Cliffs in eastern Utah are named for caps of Cretaceous sandstone that look like shelves of books. The remote area is also rich in mineral, oil and gas deposits — a fact that has led a Canadian company to open the first tar sands mine in the United States.


This video was taken by Don DeBlieux when the UGS paleontology team left the excavation site and headed home. Jim Kirkland and Scott Madsen were with him.

Don DeBlieux: “This was shot yesterday around 12:30 p.m. as we were trying to leave our Stike’s Dinosaur excavation. Our usual way out was blocked by a large mud hole from the previous day/night rain, so we tried the only other way through Yellow Cat flat. Things were looking nice and dry until we got to Yellow Cat Wash that drains a large area of the Book Cliffs. We figured this would subside and would be a better bet than the mud hole. We had to wait about 3 hours until we felt confident that we could get through safely!”
