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.
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]
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]
