Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
Overview: A beautiful forested and pool-filled canyon, hidden deep below the soaring granite walls of Clouds Rest and Mount Watkins. Miles of rock hopping and boulder scrambling, with four rappels up to 70 feet from bolted anchors. Best in late summer and fall, the inner gorge would be impassable at high water levels.
There are two approaches: 1) follow the outlet of Tenaya Lake, descending the steep slabs south of Pywiack Cascade or 2) direct descent from Olmsted Point to the base of Pywiack Cascade via a steep, brushy gully. There are also two exits: 1) climb back up and out via Snow Creek trail or 2) continue down into the Valley and car shuttle back to the start.
