The formation was named "El Capitan" by the Mariposa Battalion when it 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".
