Tennison Ridge is located in the Weiser River Basin, southeast of Crane Creek Reservoir, in the western foothills of the West Mountains. The summit lies a little more than 3.4 miles south of Riley Butte. Tennison Ridge lies on public land managed by the BLM. Google Maps will get you to the base of this remote summit. Search for either Riley Butte or the Riley Butte Road. This road traverses past the peak’s East Side.
When dry, this is a 2WD road. Follow the road south until you are due east of the peak. You will find a 4WD road leaving the Riley Butte Road at this point. Follow the road through a gate and on to the top. There are great views of the Hitt, Cuddy and West Mountains from the top, which is reached in less than a mile with just under 500 feet of elevation gain. Class 1. USGS Riley Butte
