This mano was recovered from excavations during the 1977 and 1978 Kansas Archeology Training Program field schools at the Tobias site in Rice County. Manos were likely used as the upper hand-held millstone for grinding foods and pigments. This mano was only used on one side and has some damaging from farming activities. The Tobias site is a Great Bend aspect (ancestral Wichita) village that had dense artifact deposits, house remains, and numerous deep trash-filled storage pits. The site is listed in the National Register of Historic Places.
