Earth:Prindle Volcano
Prindle Volcano is an isolated basaltic cinder cone located in eastern Alaska, United States , in the headwaters of the East Fork of the Fortymile River, approximately 80 kilometers northeast of Tok, Alaska.[1] The cone is fresh-looking and has a base approximately 900 metres (980 yards) wide. It is the northwesternmost expression of the Northern Cordilleran Volcanic Province. The cinder cone, and an approximately 11-kilometre (6.8-mile) long lava flow which breached the margin of the cone, erupted in the Pleistocene approximately 176,000 years ago.[2] The lava flow extends to the southeast, then turns southwest and continues in a river valley.[1]
Rocks forming the Prindle Volcano occur within, and penetrated through, the Yukon–Tanana upland which is a large region of mostly Paleozoic-Mesozoic metamorphosed and deformed sedimentary, volcanic, and intrusive rocks that are intruded by younger Cretaceous and Cenozoic granitic rocks.[3] Xenoliths in the volcano's ejecta provide a sample of lower crust material.[4][5]
