2021 Map of Heppner

About this map

Heppner sits at the northern edge of this high plains landscape in Fall River County, where the sprawling Buffalo Gap National Grassland dominates the central and southern terrain. The drainage patterns here are well-defined by intermittent waterways such as Hat Cr, Ash Cr, and Bitter Cr, which carve through the dry draws and grassy plateaus. This 2021 topographic record reveals a sparse human footprint, primarily consisting of remote county roads like Cascade Rd and Ash Creek Rd that connect isolated ranching parcels and public lands. In the southwest, Horse Cr and the Horse Creek Loop indicate the area's use for grazing and recreation, while Lightning Draw and Long Hollow Creek illustrate the natural erosion of the South Dakota prairie.
