About this map

The Tongue River Reservoir dominates this Big Horn County landscape, its water levels and shoreline captured during a period of industrial and topographical revision in the late 1960s and 1970s. The small settlement of Decker sits near the confluence of Squirrel Creek and the Tongue River, serving as a focal point for local history researchers and genealogists tracing rural Montana roots. Evidence of the region’s economic foundation is visible at the Tongue River Mine and various Gravel Pits scattered across the terrain.

The map records the rural infrastructure of the era, including the Squirrel Creek Sch and a Gaging Sta downstream from the reservoir's dam. Drainage patterns from the Badger Hills and numerous tributaries like Deer Creek and Coal Creek define the rugged character of the area. Significant revisions highlighted in purple indicate shifting land use and terrain changes between the original 1967 field check and the 1978 publication.
