Triceratops Gulch is a large swath of exposed rock on a private ranch near Glenrock. In 28 years of digging, over 70 sites have been identified, containing everything from complete skeletons and massive skulls to micro-sites and plant impressions.
Each generation of the Zerbst family has found significant specimens on the 7,000 acre ranch including a mummified Edmontosaurus, one of the most complete and best-preserved Triceratops skeletons ever found, and a magnificent Pachycephalosaurus skull (pictured).
