Historique
Doug Birk’s involvement with Cass county began around 1979, conducting field surveys and surface collections at Gull Lake in connection with wastewater treatment projects. Elden Johnson previously identified sites in the Gull lake area in the 1970s and Birk identified more sites from 1982 to 1984 with Northland Archaeological Services. Birk conducted surveys for sites that were disturbed by road construction, including a 1979 survey of areas around Brockway Lake. There currently are 301 known precontact or early contact (Dakota) Native American archaeological sites in Cass county. An additional 217 sites are located within the Chippewa National Forest, nearly all of which were occupied during the Woodland Period.
