1967 Map of Decker

About this map

Tongue River Reservoir dominates this Big Horn County landscape, where the waters of the Tongue River were managed for local irrigation and industry in the late 1960s. The small settlement of Decker sits at the southwestern edge of the quadrangle, serving as a hub for the surrounding ranching and mining country. The presence of the Tongue River Mine and several Gravel Pits north of Pearson points to the area's extractive economy. For genealogists and local historians, the map preserves the locations of rural infrastructure such as the Squirrel Creek Sch and the Gaging Sta along the river banks. A network of creeks, including Corral Creek, Deer Creek, and Badger Creek, cut through the drainage basins of the Badger Hills, illustrating the complex hydrology that supported homesteads and livestock in this corner of Montana near the Wyoming border.
