2020 Map of Trumbo Ranch

About this map

Fort Peck Lake defines the northern reaches of this Garfield County landscape, where the waters reach into the Missouri River breaks at Snow Creek Bay. The terrain is deeply incised by drainages such as Snow Cr, Hell Cr, and Cottonwood Cr, which carve through the high prairie towards the reservoir. The namesake Trumbo Ranch serves as a primary point of human settlement in this remote portion of Montana, situated along Trumbo Rd. To the south, the prominent elevation of Brownie Butte stands out against the network of coulees, including East Cabin Coulee. This survey illustrates the contemporary ranching footprint and the intricate shoreline of the lake, reflecting the intersection of mid-twentieth-century water management and long-standing agricultural land use patterns in the Big Sky Country.
