Follow the ridge to the summit (6,790 ft). On technical sections of rocky outcroppings, follow on the west side of the ridge.

tamanos-banshee traverse

17 miles one-way, 5 miles of cross-country travel, 5,000 feet elevation gain,
Strenuous 5 | Technical 4

Start at the Owyhigh Lakes Trailhead just after leaving a car at the Fryingpan Creek trailhead for the end of the traverse. Ascend Tamanos by way of the valley and lakes on its northern aspect before traversing to reach the 6,000-foot col on its southern aspect. From this col traverse and descend to reach Wright Creek at ~5,500 ft, then ascend to the 7,000-foot col just east of Banshee by way of the stagnant Sarvant Glacier (no glacier travel gear needed). After ascending Banshee, descend to and follow the Wonderland Trail to reach Summerland and your cars at the Fryingpan Creek Trailhead. Most of the scrambling is Technical 3 or lower in difficulty, but a short section of chossy rock on the northern aspect of Tamanos approaches Technical 4.
