Location: Redfish Lake area in the Northeastern part of the range. Popular area, but the approach valleys contain no trails and these peaks are seldom explored. Part of the Iowa Pinnacles.
Linkups: Harriets Pinnacle, Schwartz Pinnacle, Mt. Bush
Difficulty: Class 3-4, Rugged ridgeline with exposure, difficult off trail approach
Usage: Scrambling, Rock Climbing, Couloir Climbing
Terrain: Serrated Ridgeline on rotten and solid rock
Traffic: Non existent- perhaps every 10 years this ridge is explored
Summit Register: Yes
History / Etymology: Named after Bruce Adams, member of Iowa Mountaineers (Source: The Iowa Climber, Vol. 2 No. 2 Summer 1948)
Nearest Paved Roads: ID-75, Redfish Lake Road
Nearest Dirt Roads / Conditions: None
Approach Trails / Conditions: Fishhook Trail from Redfish Lodge area (Excellent)- trail peters out and becomes vague
Main Route: West Ridge Class 4- Follow the Fishhook Trail until it ends where it crosses a creek coming down from the north. Continue up the valley staying on the north side of the creek and continue to angle more north and into the side valley (Limbert Valley). Stay north of the creek coming out of Lake 9425 until about 8700 ft. Here, cross the creek and travel on the south side in a beautiful open valley. Just before another steep section of the valley (9000 ft /seasonal waterfall), cross back to the north of the creek and climb to Lake 9425. From the lake scramble south to a prominent notch in the ridge. This notch is just east of Harriet's Pinnacle. (Note: The Lopez guide has Harriet's mislabeled on the map in the book on page 165. Harriet's should be further west on the ridge. This is obvious when you see the real geography of this ridge in person). From the notch follow the ridge east to the highest point. You may need to drop to the south slopes to avoid some vertical obstacles. There will be a prominent notch just to the west of the Mt. Bruce summit block. From the west, the summit block looks difficult, but if you stay on the solid SW rib to the summit, it's no more than Class 3+.
Main Route Stats: 12.3miles / 3637 (round trip)
Average RT Time: 8-10 hours (strenuous off trail approach)
Other Routes: The Lopez guide says there's a 5.2 route. There's also a prominent couloir up the north slot to the notch just west of the summit. The south slopes leading directly from upper Fishhook Creek offers a tough approach.
Jurisdiction: National Forest (Sawtooth National Recreation Area)
Other Users / Issues: Difficult cross country travel and approach
Maps: USGS Quad- Stanley, Stanley Lake. The USGS maps do not show most of the pinnacles and mountains in the Iowa Pinnacles area.

When To Climb
Climbing Season: Summer, Fall (June-Oct)
Ideal Climbing Time: July-Sept
Nearest Weather Station: Stanley
Weather Relative to Region: located near the highest peaks in the range- expect slightly greater chance of summer T-storms in this area.
Car Camping Sites: Redfish Lake area offers lots of drive in camp sites
Backpacking Sites: Not ideal because of the difficult cross country travel (steep slopes, logs to cross etc.). Limbert Valley would make a terrific area if you could get in.
