El Capitan (Spanish: El Capitán; The Captain or The Chief), also known as El Cap, is a vertical rock formation in Yosemite National Park, located on the north side of Yosemite Valley, near its western end. The granite monolith is about 3,000 feet (914 m) from base to summit along its tallest face, and is a popular objective for rock climbers.
The formation was named "El Capitan" by the Mariposa Battalion when they explored the valley in 1851. El Capitan ("the captain", "the chief") was taken to be a loose Spanish translation of the local Native American name for the cliff, variously transcribed as "To-to-kon oo-lah" or "To-tock-ah-noo-lah" (Miwok language). It is unclear if the Native American name referred to a specific tribal chief or simply meant "the chief" or "rock chief".
The top of El Capitan can be reached by hiking out of Yosemite Valley on the trail next to Yosemite Falls, then proceeding west. For climbers, the challenge is to climb up the sheer granite face. There are many named climbing routes, all of them arduous, including Iron Hawk and Sea of Dreams.
