1971 Map of Trumbo Ranch

USGS Topo · Published 1974

About this map

Trumbo Ranch serves as the namesake focal point of this remote Garfield County landscape, situated within the expansive Charles M Russell National Wildlife Range. The northern edge of the sheet is defined by the irregular shoreline of Fort Peck Lake, where the high-water mark meets a complex network of coulees and breaks. The terrain is deeply incised by drainages such as Snow Creek, Hell Creek, and Cottonwood Creek, which flow through the arid Missouri River breaks. The topographic detail captures a transition from high prairie plateaus down toward the reservoir, punctuated by landmarks like Brownie Butte. This 1970s survey illustrates a region largely dedicated to wildlife conservation and ranching, reflecting the spare settlement patterns and rugged geography characteristic of the Big Dry country.
