Cook Spring Creek Preserve is a 4,700-acre (19 km2) nature reserve considered to be one of the richest cache of undisturbed dinosaur fossils in North America.[1] It is located near the village of Rock River, Wyoming some 40 miles (64 km) northwest of Laramie. The Preserve contains the outcrops of the Morrison, Sundance, and Cloverly formations.[2]

The preserve was established in December 2005 when rancher Allen L. Cook donated the land to the University of Pittsburgh,[3] which uses it for research and educational purposes, in partnership with the Carnegie Museum of Natural History and the University of Wyoming.[4]

The University of Pittsburgh Honors College typically offers field study in paleontology, ecology, and archaeology as well as intensive are courses in conjunction with the Department of Studio Arts.[5][6]
