About this map

Black Hills National Forest land defines this section of western South Dakota, straddling the border of Pennington and Custer counties. The landscape is dominated by a complex system of ridges and canyons, including the prominent Signal Hill and the long expanse of Elliot Ridge. Water sources are critical identifiers in this environment, with several named springs such as Alkali Spring, Mud Spring, and Tepee Spring serving as vital landmarks for those navigating the backcountry.

A dense network of Forest Development Roads and county routes like County Highway 284 provides access to the interior, tracing the paths of features like West Hell Canyon and Windmill Draw. These roads, often named after the drainages they follow, such as the North Lemming and Ditch Creek branches, reveal a modern management system for timber and recreation that respects the original topography of the Limestone Hill area.
