Great Thumb Mesa • Grand Canyon National Park History - Great Thumb Mesa carves a 20 mile arc north into Grand Canyon. It originates on the South Rim about 20 miles northwest of Grand Canyon village.

An interesting posting from the Coalition of American Canyoneers about the lack of access to the Great Thumb Mesa and across the Havasupai reservation and letters between the NPS and Havasupai.
