This bison bone rasp was recovered from the Shrope village site in Cowley County. The rasp was made by cutting grooves (36 still present) into a bison rib. Archeologists believe that artifacts like these could have been used as musical instruments by drawing a stick across the grooves. The Shrope site, a large Great Bend aspect (ancestral Wichita) village, was excavated by Kansas Historical Society archeologists and crew in 1995. Forty-one archeological features, such as storage pits, hearths, and post molds, were uncovered at the site.
