The Julesburg Project is a systematic study of the events in 1864-1865 in the aftermath of the Sand Creek Massacre.  It is primarily focused on the events that unfolded in Colorado, Nebraska, and Wyoming between the 1st Battle of Julesburg on 7 January 1865 and the 2nd Battle of Julesburg on 2 February 1865.  Throughout this period elements of the Cheyenne, Arapahoe, and Lakota Native American Nations wagged an effective, complex offensive campaign against the United States military across the Platte River valley. 

     The project uses military theory, archaeology, history, geography, and spatial analysis in its approaches.  It does this using a level of war analysis that looks at events at the strategic, operational, and tactical levels of war.  The project conducts fieldwork, analyzes museum and private collections, and conducts original historical research to understand the events.  It also relies heavily on technology such as LiDAR, drones, and GPR to further assist in its analysis. The Julesburg Project is led By Ray Sumner, a Ph.D. candidate in the Department of Anthropology and Geography at Colorado State University.
