The cone is fresh-looking and has a base approximately 900 meters wide. It is the northwesternmost expression of the Northern Cordilleran Volcanic Province. It is a basaltic cinder cone, with lava flows extending approximately 11 km, which erupted in the Pliocene approximately 176,000 years ago. Rocks forming the Prindle Volcano occur within, and penetrated through, the Yukon-Tanana Terrane which is a large region of mostly Paleozoic-Mesozoic metamorphosed and deformed sedimentary, volcanic, and intrusive rocks that are intruded by younger Cretaceous and Tertiary granitic rocks. Xenoliths contained in the volcano's ejecta provide a sample of lower crust material
