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. 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. Xenoliths in the volcano's ejecta provide a sample of lower crust material.
