About PCRG

Paleocultural Research Group is a member-supported, 501(c)(3) nonprofit that conducts scientific research, trains students, and educates the public on the archaeology of the Great Plains and Southern Rocky Mountains. PCRG’s public archaeology projects use state-of-the-art field and lab techniques to study human communities and their relationships to the natural environment, from North America’s earliest Native American inhabitants to nineteenth-century traders and settlers. PCRG broadly disseminates the findings of its projects to professional and public audiences, raising awareness of Plains and Rocky Mountains archaeology and fostering preservation of the unmatched archaeological resources those regions contain.

Founded in 1996, PCRG maintains long-term partnerships with a diverse mix of federal agencies, state agencies, and universities. PCRG members, research affiliates, and staff are experienced in the design and implementation of cooperative research and education programs featuring extensive public involvement. PCRG public archaeology projects have taken place in Colorado, Wyoming, North Dakota, Nebraska, Arizona, and Texas. PCRG staff have developed interpretive signs, exhibits, and public school curricula and presented public lectures on the organization’s work in a variety of settings. PCRG also trains undergraduate and graduate anthropology students in archaeological field and lab methods.

Mark Mitchell, Ph.D.

Research Director

Dr. Mark D. Mitchell is PCRG’s Research Director. Previously, he worked for several cultural resource management firms and for the USDA Forest Service in Colorado, Wyoming, and Kansas. Mitchell holds a Ph.D. in Anthropology from the University of Colorado at Boulder and has more than 35 years of experience in archaeological field and laboratory research. His interests span the archaeology of two different regions: the Northern Great Plains in central and western North Dakota and the Southern Rocky Mountains in Colorado and New Mexico. Mitchell’s Southern Rockies research focuses on American Indian land use in the San Luis Valley and adjacent mountains. His Northern Plains research focuses on the political and economic development of post-A.D. 1200 farming villages of the Missouri River valley. He also studies historic American Indian rock art and the history of archaeology. His research has appeared in Quaternary International, Plains Anthropologist, Antiquity, American Antiquity, Southwestern Lore, Colorado Archaeology, and in a number of book chapters. He is the author of Crafting History in the Northern Plains: A Political Economy of the Heart River Region, 1400-1750 (University of Arizona Press, 2013) and co-edited Across a Great Divide: Continuity and Change in Native North American Societies, 1400–1900 (University of Arizona Press, 2010).
