About this map

The Crow Indian Reservation Boundary runs through the southern portion of this landscape, marking a significant jurisdictional division in Big Horn County. Settled within this rugged Montana terrain, the Spring Creek School stands as a focal point for the local rural community near the eastern edge of the survey. The geography is defined by the Red Hills and several vital drainage systems, including Sarpy Creek and Plum Creek, which have carved out the local topography.

Evidence of resource exploration is scattered across the hills, with multiple Gravel Pit locations, Prospects, and a prominent Pipeline cutting across the north-central sections. These industrial markers, alongside various Drill Hole and Well sites, indicate a period of active subsurface assessment. The intersection of the Base Line with the local township grids provides a clear framework for those tracing land ownership and early 1970s land use patterns in this part of Big Horn.
