2011 Map of House Mountain

About this map

House Mountain dominates the western portion of this Boise National Forest landscape, where steep drainages feed the expansive Anderson Ranch Reservoir. In 2011, this area served as a significant recreational hub for Idaho outdoorsmen, anchored by a series of waterside sites including Castle Rock Campground, Evans Creek Campground, and the Little Wilson Creek Campground. The Rhead Dam sits near the reservoir's western arm, managing the flow of the South Fork Boise River system. Moving north from the shoreline, the terrain climbs toward White Flat and the high ridges defined by House Mountain Rd. A dense network of seasonal drainages such as Fall Creek, Myrtle Creek, and Knox Creek carve through the foothills, illustrating the complex hydrology that feeds the reservoir. For those tracing the human footprint in the backcountry, the presence of the Fall Creek Lodge and Ice Springs Campground highlights the established corridors of access into the Elmore County wilderness.
