2012 Map of La Plant SW

About this map

Agneau Ranch and HTriangle Ranch sit within the sparse, drainage-heavy landscape of Dewey County during the early 21st century. The terrain is defined by a complex network of intermittent waterways that feed into larger systems, including Virgin Cr and Stove Cr in the northern half of the quadrangle. Further south, the map details the headwaters of the Willow Creek system, split between E Br Willow Cr and W Br Willow Cr. This area of the Cheyenne River Reservation shows a transition toward more centralized ranching operations, with CO Hwy-15h providing the primary transit corridor across the northern plains. The detailed mapping of small local features like Parkers Cr, No Heart Cr, and Scatter Butte Cr provides a precise record of the traditional land-use patterns and seasonal hydrology in this part of South Dakota.
