2011 Map of Big Rock

About this map

Big Rock stands as a focal point in this portion of Glacier County, where the plains meet the complex drainage systems of the eastern Rocky Mountain front. The landscape is defined by the winding course of the Two Medicine River and its major tributary, the South Fork Two Medicine River, which carve through the terrain alongside secondary waterways like Depot Creek and Deep Creek. This 2011 survey captures the area's rural character, emphasizing a transition from open range to established ranching landmarks like the Magee Ranch. Local transit is represented by a network of secondary routes including Heart Butte Rd and the Heart Butte Cutoff, providing essential connectivity through this high-plains environment near the Blackfeet Indian Reservation border. The map documents a sparse but vital human imprint, with named roads and family-associated ranches serving as the primary geographic anchors.
