Elevation: 6,929 ft
This peak is not in the book.
Coolwater Mountain is the westernmost high point of the divide separating the Selway and Lochsa Basins. The mountain is not actually in the high crags but is a western extension of the Divide. Still, Coolwater Mountain is a noteworthy summit because of its dramatic vertical rise of nearly 5,500 feet above the Selway/Lochsa confluence and relatively substantial prominence of 1,129 feet. Also, Coolwater Mountain retains one of the very few fire lookouts still in operation. The mountain’s broad south aspect holds snow well into the summer and offers a beautiful and dominating view for miles onto the Camas Prairie to the west. USGS Coolwater Mountain
The mountain is a significant trail hike (more than one vertical mile) from the canyon bottoms on both its north and south sides. Alternatively, drive a road that goes almost to the top along Coolwater Ridge. But, it is not easy…the road is one of the most rugged anywhere, is virtually undrivable to many vehicles, and is not for the faint of heart.
Formed of crumbly granite and quartz-derived material, the ridge crest runs east-west for about 7 miles. The bulk of the ridge sits above 6,000 feet. The north side is forested with subalpine fir. However, much of the area is brush after huge fires in the early 1900s. The south side is a beautiful parkland of open subalpine fir scattered across lovely verdant slopes of subalpine grasses, sedges, and beargrass. Lower slopes are covered by the inland coastal refugia rainforest famous in the Clearwater Basin. Some less common subalpine coastal disjunct are also found on the upper slopes.
Spectacular view abound! To the west, you can see far beyond the Camas Prairie into the big canyon country of Oregon and Washington States. To the north, look into the northern Clearwater Basin and possibly a few points within the St. Joe. To the south, view the higher summits on the South Fork Clearwater/Salmon Divide. On a clear day, you can see peaks south of the Salmon, the Seven Devils, and possibly beyond the Devils. But the eastern view is the best, with the high-central Selway Crags in the foreground and the higher expanse of the Montana Bitterroots far beyond.
From the lowest elevation trailheads in the Lochsa and Selway Canyons, you will climb over a mile to reach the summit. Though not technical, these routes are long, strenuous climbs generally used by outfitters during hunting season. The Coolwater Road/FSR-371) allows you to drive almost to the top. At the start the road will look like a driveway to a private residence, but it is well signed. The lower mile of this road passes through private property so please stay on the road in this area.
Routes (Class 1)
Coolwater Road/FSR-317: Access Coolwater Road from Selway River Road, about 1 mile upstream from Lowell and US-12. Narrow and twisty, the road follows Coolwater Ridge. The road is in fair shape to around Andy’s Hump where it breaks out into the open slope parklands of Coolwater Mountain. Here, the road is very rocky with some steep pitches.
It is not possible or safe to drive this road without high clearance and preferably 4WD. Nor is it possible to drive all the way to the top, without actually driving on a trail, but “rough” driving can get you very close. Alternatively, park at the saddle on the east side of Andy’s Hump and either walk the road to the summit or walk the ridgeline. Either way requires about 1.5 miles of hiking.
Lochsa Trails (North Side): Reach Coolwater Mountain from US-12 along the Lochsa River via the following trails: FST-341, Kerr Creek Trailhead, FST-337/332, Apgar Campground Trailhead and FST-334 Trailhead near Coolwater Creek.
Selway Trailheads (South Side): Trails from the Selway bottoms ascend to Coolwater Mountain (or connecting points) along FSR-317. These points include FS-735, 3C Camp Trailhead, FST-703 Boyd Creek Campground Trailhead, and FST-704 Clover Campground Trailhead.
