2021 Map of Ainsworth NW

About this map

Antelope Peak stands as a prominent landmark in this section of Brown County, overlooking a complex network of eroded drainages and deep coulees. The landscape is defined by the sharp descent from the southern plains into the broken terrain of the Niobrara River valley outskirts, where features like White Cliffs and Horsethief Canyons reveal the underlying geology. Named drainages such as Bill White Canyon, Broyer Canyon, and Lessig Canyon cut through the elevation, carrying seasonal runoff toward the perennial waters of Plum Cr. The map details the transition from high-altitude tablelands to the dissected breaks, showing a territory primarily shaped by water erosion and ranching access. While few structures are named, the presence of specific family-named landmarks like Hurlbut Canyon and Wood Canyon provides a topographic baseline for local land ownership and historical land use patterns.
