2011 Map of Big Sheep Mountain NW

About this map

Ash Creek Rd and Cedar Creek Rd provide the primary access through this high plains landscape in eastern Montana. This 2011 survey by the U.S. Geological Survey focuses on the complex drainage network of McCone County, where numerous intermittent waterways converge. The most significant hydrological feature is the Tusler Creek Oyargers and Pardies Dam, a named infrastructure point along Tusler Creek. The map documents the winding courses of Ash Creek, Pasture Creek, and East Duck Creek, illustrating the natural water management patterns essential to this region. This detailed documentation of ranch roads and water features reflects the ongoing agricultural and land management priorities of the early 21st-century American West.
