Bull Creek Site

In 1981, the National Park Service recognized the Bull Creek area at the foot of the Henry Mountains as a national archaeological treasure. But for reasons unknown, the evidence supporting the Bull Creek Archaeological District was lost, and the location of more than a hundred National Register sites is not known today. Since 2023, CPAA, in partnership with the Bureau of Land Management (Richfield Field Office) and the Utah State Historic Preservation Office, has been teasing out clues hidden in forgotten archives to re-identify and re-document the lost sites.

Grand Staircase

CPAA and its executive director have worked closely with Grand Staircase-Escalante National Monument since its creation in 1996, producing comprehensive overviews of the region’s prehistory in 2001 and 2021.

Utah Universities

Since 2005, the University of Utah and, for more than a decade, Southern Utah University have partnered with CPAA to provide hands on field training and advance projects like the Bull Creek Site Re Identification Project. Led by Jerry D. Spangler, with Emily Dean serving on the CPAA board, these collaborations prepare the next generation of archaeologists.
