This is a curated collection of CRSI materials intended for public use, containing no archival records of the Institute. The collection consists entirely of born-digital items, including presentations, abstracts, maps, and research papers about the geology, archaeology, and history of the region around Cherokee Ranch in Douglas County.

Biographical Note
Allan J. Koch (1943-2019), better known as “Al,” grew up in Iowa where he was a star basketball player and student athlete at Iowa State University.

Koch retired to Castle Pines in 2000, not far from the historic Cherokee Castle and its 3400 acres of protected wildlife sanctuary. Koch first became involved with the Cherokee Ranch and Castle Foundation in 2003 as a volunteer. He helped create the Cherokee Ranch Science Institute in 2013 and served as its first director.
