Spring Hill is located east of the main Lost River Range Crest, a couple of miles north of Horseheaven Pass. It abruptly rises up above the Pahsimeroi Valley and is the highest point of a somewhat-isolated group of 7 peaks, 5 of which are ranked summits. As a result of its prominence, Spring Hill was used as a surveying site as early as 1915. USGS Spring Hill
Northwest Ridge, Class 2 by Derek Percoski
From Doublespring Pass Road [(C)(3) on Page 293], turn east onto FS-117 toward Horseheaven Pass. Reset your odometer. At roughly 1.2 miles, the road forks. Go left/northeast onto FS-268. At 2.5 miles, go left at another junction. At 4.6 miles, the road tops out at 8,700 feet directly on the Northwest Ridge of Spring Hill. A high-clearance vehicle is required and 4WD is recommended.
From the road, it is just over a half a mile with 754 feet of elevation gain up Northwest Ridge to the summit. The occasional game trail can utilized for parts of the climb.
