The first ascent of the summit was made in August 1898 by William Wallace Bass and George Wharton James.[5] James originally named it Mount Observation, but wrote that Indians called this mountain "Hue-tha-wa-li" (pronounced "we-the-wally"), which means White Rock Mountain.[9][10] Some sources state that "Huethawali" is the Native American word for "observation point", while other sources state it translates as "white tower" or "white rock mountain" in the Havasupai language.[3][11][5] This butte's name was officially adopted in 1932 by the U.S. Board on Geographic Names.[3]
