2024 Map of Willow Creek Dam SW

About this map

Lodge Grass Canyon and the surrounding high-altitude breaks of Big Horn County define this landscape on the Montana-Wyoming border. This modern survey illustrates a rugged drainage network where Lodge Grass Creek and its many tributaries, such as Percheron Creek and Coyote Creek, have carved deep into the limestone and shale of the northern Bighorn Mountains. The map reveals a remote ranching and grazing landscape characterized by prominent landmarks like The Mesa and Tepee Pole Ridge. Transportation is minimal, with Marble Quarry Rd providing one of the few named access points into the high country. Notable topographical features like The Beaver Slide and Salt Ridge suggest a terrain shaped by steep elevation changes and traditional migration or herding routes across the ridges, providing a clear record of the area's natural boundaries and water sources.
