Fan Island is a 5092feet summit located in the Grand Canyon, in Coconino County of northern Arizona, US.[3] It is situated two miles south of Dutton Point, 2.5 miles west-northwest of Dox Castle, and 1.6 miles south-southwest of Masonic Temple. Topographic relief is significant as it rises 2900abbr=offNaNabbr=off above the Colorado River in 1miles. Fan Island was so named because the flat top resembles an unfolded hand fan.[5] According to the Köppen climate classification system, Fan Island is located in a cold semi-arid climate zone, with precipitation runoff draining south to the Colorado River via Hakatai Canyon from the west aspect, and Burro Canyon from the east aspect.[6] This butte is an erosional remnant composed of Redwall Limestone overlaying the Tonto Group.[7]
