2017 Map of Smiley Canyon
USGS Topo · Published 2017About this map
The Oglala National Grassland and Nebraska National Forest converge in this corner of Sioux County, where the High Plains transition into the broken, high-relief terrain of the Pine Ridge. The topography is defined by the namesake Smiley Canyon and the headwaters of several drainages, including the White River, Dead Mans Cr, and multiple forks of Soldier Creek. This area illustrates the management of water and transit in a semi-arid landscape, with Dunlap Reservoir and Carter P Johnson Reservoir providing essential water storage.
