Vulcan's Throne is a cinder cone volcano and a prominent landmark on the North Rim of the Grand Canyon in Arizona, US. Vulcan's Throne, about a mile (1.7 km) west of Toroweap overlook, is part of the Uinkaret volcanic field.[2] The journals of traveler George Corning Fraser record a trip to the summit of Vulcan's Throne in 1914. At the time, the surrounding area was used for sheep grazing, and a small reservoir had been constructed at the base of the volcano.[3] Fraser wrote that
Vulcan's Throne is a pure cinder cone covered with scoriae, cinders, clinkers and peperino lying loose on the surface, with a slope, as near as I could measure, from 28° to 31°. A little sage, many cacti and perhaps some other similar low plants grow on it, but otherwise nothing. Climbing it was like ascending a sand-dune. Every step forward involved slipping half way back and boots were soon filled with painful bits of stone.
— George Corning Fraser, 17 July 1914, Journeys in the Canyon Lands of Utah and Arizona, 1914 - 1916, pp 25-26
The cinder cone was formed during the Quaternary Period, and is cut by recent movement on the Toroweap Fault.[4]
