Elevation: 7,700 ft
This peak is not in the book.
House Mountain is located in an isolated position southeast of Prairie, Idaho. While not an exceedingly high summit, it towers over the South Fork Boise River’s deep canyon which is on its southern flank and has over 1,700 feet of prominence.. The peak is a former fire lookout site and a road, FS-137, leads to its summit. The view from the summit is impressive. I have not found any historical information on the lookout but there are substantial concrete foundations for the lookout, an outhouse and another building on the summit.
FS-128 runs east to west between Fall Creek and the Prairie area. The House Mountain Road leaves FS-128 at the high point between the two drainages at a marked intersection, crosses a three low ridges and then climbs up the peak’s north side. Once it reaches the peak’s west ridge it turns back and climbs up the southern slopes to the summit. In 2015, the road was smooth and well graded until the last mile where it becomes rocky. There are a number of side roads that leave FS-137 but none are as well used as FS-137.
From the FS-128/FS-137 junction it is 5.3 miles to the summit. The road has plenty of ups and downs for the first two miles as it crosses the low ridges and gains most of its elevation in the last three miles.
Dan Robbins climbed it from the Prairie Road during a May outing when there was plenty of snow. Check out his trip report.
