Peak 10552, Sentinel Turret, Found Arrow Spire. A second pinnacle on the east side of Sentinel Turret, about 300 feet below its summit, was found and climbed on August 26 by Ted Vaill and Brad Merry. Although it overhangs on all sides, a moderate single-pitch route was climbed from the notch separating the Spire from the face of the Turret; the notch was reached by scrambling up a talus couloir east of the Spire and then traversing back to the Spire on wide ledges. Descent from the one-yard square summit was made via rappel from a piton.
