Summer Archaeological Field Research Programs Archeological Research Institute Summer Field Programs Join ARI archaeologists in the field as we investigate ancient human habitations dating back to 11,000 years ago. ARI offers hands-on experience in archaeological site excavation, on the site as well as in the classroom. ARI excavations began on the site in 1996. Located in northwestern Colorado on Douglas Creek, La Posada has provided valuable information about the Archaic, Fremont and Numic peoples who inhabited this corner of the state between 4,500 and 500 years ago.
College credit is available.
Year 2000 excavations not presently scheduled. This is a rare find, a prehistoric site in northwestern Colorado dating back as much as 11,000 years ago, representing an occupation of Paleoindians who hunted extinct forms of mammoth and bison. It is one of the few deeply buried sites of Folsom and possibly Clovis peoples in North America. Yampa, where the excavation program began in the spring of 1997, promises to yield important information about these early big game hunters. College credit is available.
