One of the unique and outstanding holdings of the Archives and Special Collections Department is a set of hand-drawn maps executed by a young Army lieutenant named Caspar Collins, depicting camps and stations once found in areas of the Western Plains. Caspar Collins's mother donated to Colorado State University Caspar's expedition maps, along with several items belonging to his father. The Archives and Special Collections Department possesses no deed of gift for the Caspar Collins maps; therefore, the exact date of accession cannot be determined. The original maps are fragile and use is therefore limited. However, there are other types of media available for researchers to view. In addition to the digital images available for access on this site, there are negative photocopies of all the maps, as well as glossy photocopies of each individual station map. These have also been preserved on microfiche. Potential researchers should contact the department to arrange a visit.
