Prindle Volcano

From Wikipedia, the free encyclopedia

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. The cone is fresh-looking and has a base approximately 900 meters wide. It is the northwesternmost expression of the Northern Cordilleran Volcanic Province. The cinder cone, and an approximately 11 km-long lava flow which breached the margin of the cone, erupted in the Pleistocene approximately 176,000 years ago.[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.[2] Xenoliths in the volcano's ejecta provide a sample of lower crust material.[3][4]
