2020 Map of Griffin Coulee NW

About this map

Reservation Creek Rd and Jones Ln provide the primary access through this dissected landscape where the boundaries of Rosebud Co and Treasure Co meet. The terrain is defined by a dense network of coulees and intermittent streams that drain toward larger regional basins. Among these prominent drainage features are Cache Coulee, Prairie Dog Coulee, and Wyant Coulee, each carving distinct paths through the high plains. The map illustrates the sophisticated Public Land Survey System (PLSS) grid, with sections clearly marked within t6n r38e and t5n r39e, reflecting the orderly division of the American West. Hydrological features such as Reservation Cr and Blacktail Cr highlight the reliance on natural watercourses in this arid environment, providing essential context for land use and ranching history in this part of Montana.
