"We are pleased to present "A Report of Archeological Investigations, Pipestone National Monument, 1965 and 1966," by John S. Sigstad. Since completing this report, Mr. Sigstad has continued his interest in catlinite and is currently engaged in a study involving the time of initial quarrying at Pipestone and the patterns whereby the soft red stone was distributed throughout portions of North America. Mr. Sigstad is currently Assistant Professor of Anthropology at the University of South Dakota, Vermillion, South Dakota...."
Recent investigations in Pipestone National Monument, Minnesota tend to support the assumption that the aboriginal utilization of catlinite was, in the main, rather recent. The evidence suggests that the quarrying of catlinite in this area was primarily an activity of protohistoric and historic peoples. There is also some evidence to suggest that aboriginal activity in the area has greater time depth than previous suggestions would indicate, but the precise relationship between these earlier activities and the utilization of catlinite remains to be clarified.
