Near the north-west corner of the RM on the eastern shore of Kippan Lake,^[9] along the border of Moose Mountain Provincial Park, is Saskairie (49°42'24.0"N 102°23'06.1"W). Saskairie is a Nature Conservancy of Canada property that was established in 1974 by Prairie Lore and Living Society on three-quarters of a section of woodland wilderness. Prairie Lore and Living Society was formed in 1972 as a non-profit organisation. The three founding members were Jack MacKenzie, Don Stewart, and Nora Stewart.

"A place like Saskairie with its wilderness aspects of beauty, solitude and peace can only become more and more valuable in our fast-paced technological society," Jack MacKenzie^[10]

The park was originally created to provide a year-round outdoor and environmental educational facility for students. In 1977, a cabin was built that could accommodate 32 people.
