Dry and clear conditions. Excellent conditions for October! Went via Chester Lake, Elephant Rocks and Three Lakes Valley. Up a steep scree slope, climbers left, with Rock falls hazard. Traversed climbers left up and across several bedrock ribs , up shifting talus blocks to the summit. Arrived there late in the day, didn't hang out long, returning same way we came up. Moderate scrambling down. Got dark when we passed Chester Lake on the way back to cars; used headlamps . I want to repeat this climb .
