2017 Map of Big Rock

About this map

The Two-Medicine River and its S Fork Two-Medicine River branch across the high plains of Glacier County, defining the drainage patterns south of the Big Rock settlement. This landscape, surveyed in the early 21st century, is characterized by a network of local roads that bear the names of regional families and nearby landmarks, such as Morning Gun W Rd, Jerry Show W Rd, and the Heart Butte Cutoff. Small water bodies like Depot Cr and Elk Cr dot the northern reaches, while the terrain's topography reveals the complex glacial history of the area near the eastern edge of the Rocky Mountains. The presence of RR Rd suggest former or existing corridors through these ranching and tribal lands, where wide-open spaces are segmented by section lines of the Public Land Survey System.
