About this map

The White River carves a winding path through this central South Dakota landscape, defining the border between Lyman and Tripp counties. This mid-century survey, updated with late-1970s aerial data, reveals a ranching economy centered around the riparian flats of Gunny Sack Bottom and the broad reaches of Star Valley. Several established family operations are documented, including the Christensen Ranch and Kewley Ranch, which sit near the river's edge.

Local infrastructure for the rural community is visible through the presence of the Edna Sch and named topographical regions like Sylvia and Edna. Beyond the primary river, the land is drained by numerous seasonal and perennial watercourses such as Mill Creek, Dog Ear Creek, and Old Lodge Cr. Significant geological features and water sources like the Flowing Well and various Gravel Pits highlight the intersection of natural resources and early land use in this Great Plains region.
