On June 21, 1925, Detroit-area people of Finnish descent purchased this land and built a summer camp where they could share the traditions of their native Finland. The Detroit Finnish Co-operative Summer Camp Association organized to maintain the camp and promote the social, intellectual, cultural, and physical welfare of its members. The founding members planned and built the campground, constructing the first sauna in 1926 and the existing dance hall in 1927. Summer activities included athletic contests, swimming programs, plays, and the annual celebration of Juhannus, the Finnish midsummer festival.
