Introduction:
Two of the most prominent landmarks are Vulcan's Throne, a 73,000 years old cinder cone on the north rim, and Vulcan's Forge, a small volcanic neck erupted within the Colorado River, 1000 m below.Most of the Uinkaret field lies north of the Grand Canyon on the Uinkaret Plateau between the Toroweap and Hurricane faults. Most of the Uinkaret volcanic field is older than 10,000 years, but some activity has occurred even only about 1000 years ago. The lava flow from Little Springs, south of Pliocene Mount Trumbull, has a cosmogenic helium age of 1300 +/- 500 years BP. Pottery sherds dated at between 1050 and 1200 AD were found within the Little Springs lava flow, which occurred about the same time as the Sunset Crater eruption in the San Francisco volcanic field to the SE.
