Creator Sketch

The Peabody Museum-National Geographic Early Man Expedition at Hell Gap, Wyoming was a six-year (seasonal) archaeological study of the prehistory of the high plains of eastern Wyoming. The principal investigators on the expedition were Henry T. Irwin of the Peabody Museum, his sister, archaeologist Cynthia Irwin-Williams,and George A. Agogino of the Eastern New Mexico University. Hell Gap had continuous human occupation for 11,000 years and was an excellent site example of tool development.
The main objective of the expedition was the systematic removal of enough material from the various cultural complexes represented at the site (Folsom and Clovis, Midland, Agate Basin, Hell Gap,Cody, and the Frederick) to identify their archaeological content. The main thrust of the work was to reconstruct a lifeway on the Great Plains that existed between 9000 B.C.and 5000 B.C.The study included not only archaeological excavations, but climatic interpretations based on geology and geomorphology by C. Vance Haynes,University of Arizona, assisted by Dr. John M. Saul, Massachusetts Institute of Technology.Many students also assisted on the site.

Scope and Contents

The expedition records contain evidence of the many activities that were carried out on site. Series include field notes, site cards, clippings, correspondence,personnel records, manuscripts and writings,photographs,reports and proposals,and financial records.
Fieldnotesare recorded in site notebooks by Irwin. As well, the collection includes copies of the site cardsgenerated by Irwin. Some personal material is included: clippings of favorite poems and some of Irwin's correspondence with friends and family members. Other correspondence details the expedition logistics and progress in letters to and from the Peabody Museum. A good deal of the personnel records document the process by which student workers were hired each summer. Manuscripts and writings contain drafts of several articles written by Irwinand Irwin-Williams. Photographic material is comprised mainly of a "photo journal" compiled by Cynthia Irwin-Williams which depicts both the archaeologists' living conditions and the excavations themselves. In more formal efforts, expedition reports and proposals drafts reveal the work that went into documenting the expedition for the granting agencies, and copious financial records show the level of accountability necessary to recoup expenses.
