Sage Hen Benchmark sits north of Grouse Peak on a high ridge in the northern Pahsimeroi Mountains. It is most easily climbed from a nearby 2-track ridge road (FSR-111). USGS Grouse Peak

Access
Same as for Grouse Peak. Hike (or drive) north on FSR-111 from Grouse Peak all the way to the crest in the road as it skirts the east side of Sage Hen Benchmark.
Southwest Ridge, Class 1
The Climb
From FSR-111, bushwhack north up through sagebrush to reach the Sage Hen Benchmark. However, the high point seems to be about 100 feet or so northeast of the Sage Hen Benchmark (official LOJ high point). The benchmark location looks (and measures) about five feet lower than the actual high point. The USGS benchmark is gone but I built a summit cairn atop the official summit near the spot where the benchmark used to be.
