2021 Map of Two Lance Lake

About this map

The Little White River and Stinking Water Cr define the northern drainages of this high plains landscape along the county line shared by Oglala Lakota and Bennett counties. The terrain is marked by a complex system of semi-permanent wetlands and small basins, including Two Lance Lake, Alkali Lake, and Posey Lake in the southern reaches. This modern topographic study reveals a sparsely populated area where land use is oriented toward water resources and grazing. A single historical marker, the Knight Cem, sits in the northwest quadrant, providing a rare genealogical point of reference in an otherwise open prairie environment. The map details the transition from the river valley to the pothole-studded tablelands, capturing the contemporary state of this remote South Dakota interior.
