1971 Map of Bison Bone Reservoir

USGS Topo · Published 1974

About this map

Bison Bone Reservoir sits at the center of this remote Phillips County landscape, which is defined by an intricate drainage system typical of the Missouri River breaks region. Surveyed in the early 1970s, the terrain is carved by the winding paths of Dry Fork Creek and Beauchamp Creek, which flow through deeply incised valleys before joining the larger drainage basins to the south. The map reveals a land focused on water management and ranching, evidenced by several small-scale impoundments like Pep Reservoir and a Private Reservoir located along the southern reaches. This era of mapping documents the seasonal waterways of Trine Creek and Spring Creek, providing a detailed look at the land's hydrology and fence lines before modern changes. The sparse naming of features emphasizes the open, agricultural character of this Montana high prairie.
