2017 Map of Big Hill

About this map

The Yellowstone River snakes through the southern edge of this Custer County landscape, a vital watercourse for the ranching and aviation operations that define the area. To the north, the terrain rises toward the prominent summit of Big Hill, with a complex network of seasonal drainages including Sunday Cr, N Sunday Cr, and S Sunday Cr carving through the high plains. This map illustrates the transition from the river valley floor to the dissected uplands, marked by local landmarks such as Frank Wiley Field and the Fort Keogh Bridge. Historical infrastructure is evident in the alignment of Ft Keough Rd and Sheffield Rd, tracing routes along the river and the adjacent Reservation Cr. The presence of Cotton Cr and Crooked Cr further indicates the intricate drainage system that has historically dictated land use and settlement patterns in this part of Montana.
