Peak 7081 and Rock Knoll can be combined via a 10-mile loop trail with a few different options. The version described is shown on the track which uses trail and off-trail hiking. From Bannock Highway in Pocatello, take Gibson Jack Road west to where it ends at a large parking area. Use Gibson Jack Trail/FS-014 to access the Upper Gibson Jack Trail/ FS-015. Follow this trail to about 6,938 feet. Turn north and leave the trail to reach the summit of Peak 7081.
Return to the trail and use it to descend to Elk Meadows where it ends at jeep road FS-022. Follow FS-022 to the southwest approximately 0.5 miles to reach an old, revegetated (but still discernible) spur trail to the northwest toward Rock Knoll. Follow this spur trail (which parallels a fence line) as it continues above treeline. Cross the fence and continue to the summit of Rock Knoll, hiking on a short section of stable talus.
From the summit block, descend north through a short section of rock ledges and follow the ridge which turns to the east at around 7,100 feet. Continue to descend on the ridge through rocks, low shrubs, and grasses looking ahead for the opportunity to connect to FST-014, which becomes more evident as you descend the ridge. Once you reach FST-014, follow it back to the parking lot. This loop is a little more than 10 miles. Class 2. USGS Pocatello South
