CBI Benchmark is a pleasant peak located in the upper reaches of the Jump Creek drainage west of US-95 and east of the Idaho-Oregon border. This area burned hot in 2015 but appears to be recovering nicely. This peak can be climbed from most directions. Dan Robbins picked out the route shown below based on the fact that it provided the best access. This is open country and route finding is not difficult. We could have driven closer to the peak but decided to make the hike longer. All in all we hiked 4.5 miles round trip. On our walk we had a 300 foot descent into Jump Creek preceding the final climb to the summit. Nice views of big country from the top. Class 2 after leaving the two track road. USGS Jump Creek Canyon
To reach the peak drive 16.1 miles south of the US-95/ID-55 junction and turn west onto the Sand Basin Road (unsigned). This road will be difficult to drive if wet. Follow the road to a junction shown on the map below. From this point a 4WD is recommended.
