Geology
editSentinel 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
editThe 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]
