Sentinel Rock is a granitic peak in Yosemite National Park, California, United States. It towers over Yosemite Valley, opposite Yosemite Falls.[5] Sentinel Rock lies 0.7 miles (1.1 km) northwest of Sentinel Dome.

Geology

Sentinel Rock formed when masses of rock split off Yosemite Valley's south-side cliff, along steep joints trending nearly east–west. This formed the near-vertical north face of Sentinel Rock.[6]

Climbing

The most famous climbing route is the Steck-Salathé route, which is rated a class 5.10b G A0.[3]

Climber Derek Hersey died while attempting to free solo climb Sentinel Rock in 1993.[7]
