1971 Map of Trumbo Ranch

USGS Topo · Published 1987

About this map

Charles M Russell National Wildlife Refuge dominates the northern reaches of this Garfield County landscape, preserving the wild character of the Missouri River breaks. The 1971 topography, with 1982 revisions, illustrates the complex drainage system feeding into the southern edge of Fort Peck Lake. Long, winding waterways like Snow Creek, Hell Creek, and Cottonwood Creek have carved deep incisions through the terrain, illustrating the dramatic erosion characteristic of this region. The presence of Trumbo Ranch near the center of the map highlights the enduring legacy of Montana's ranching heritage in an area otherwise defined by protected federal lands and the prominent silhouette of Brownie Butte. These named coulees and springs provide a detailed record of water sources that were essential for early settlers and livestock in the semi-arid northern plains.
