1965 Map of Porcupine Creek

About this map

The Mission Range and Flathead Range define this high-altitude landscape in western Montana, where the boundary of the Flathead Indian Reservation meets extensive public timberlands. Surveyed in the mid-1960s, the map reveals a wilderness primarily managed as the Flathead National Forest and the Swan River State Forest. The drainage patterns are intricate, with numerous westward-flowing streams such as Blue Bay Creek, Teepee Creek, and Talking Water Creek cutting through the steep slopes.
