1970 Map of Half Moon Canyon

USGS Topo · Published 1973

About this map

Lewis And Clark National Forest dominates the high-altitude landscape of the Big Snowy Mountains in this central Montana survey. The terrain is defined by dramatic vertical relief, rising from deep drainage systems like Big Canyon and Stovepipe Canyon to prominent summits such as Greathouse Peak and Old Baldy. The map documents a sparsely settled frontier character, where human presence is primarily marked by isolated landmarks like the Lewis Ranch and seasonal transportation routes. A complex network of Pack Trails and Jeep Trails provides the only access into the interior, connecting remote water sources like Rogers Spring and Big Spring Fork Middle Fork. This 1970s record preserves the intricate hydrography of the region, including the headwaters of Swimming Woman Creek and Half Moon Creek, as they carved their way through the limestone ridges and coulees long before modern development altered these remote drainages.
