USGS geologists view the informational sign at the quarry upper overlook in July 2024. The sign describes the history of Professor O.C. Marsh and Marshall P. Felch, the namesakes of the quarry, who worked together to excavate and study dinosaur bones. The sign features a photograph by Israel Cook Russel, a USGS Geologist, in July 1888.

NUSO researchers supported the USGS National Cooperative Geologic Mapping Program’s Geoheritage Sites of the Nation Project in July of 2024 with the collection of UAS-based high-resolution imagery of the Marsh-Felch Dinosaur Quarry site at the Bureau of Land Management (BLM) Garden Park Fossil Area.
