2011 Map of Fallert Springs

About this map

Pass Creek Lake sits as a central water feature in this high-altitude landscape where the headwaters of several drainages diverge. The drainage patterns are clearly defined by the Middle Fork Pass Creek and South Fork Pass Creek, which carve through the terrain near notable landmarks like Middle Fork Eightmile Canyon. This 2011 survey by the U.S. Geological Survey captures a sparsely settled region of Idaho, characterized by deep canyons such as Sunny Bar Canyon and a network of Forest Service or local access roads including 157 and 802. The mapping detail focuses heavily on the intricate hydrography of the area, tracing the winding paths of Boulder Creek, Rocky Run Creek, and Uncle Ike Creek as they navigate the basin.
