BackgroundMount Gordon is the most prominent of a group of Pleistocene and Holocene cinder cones in the northern Wrangell Mountains between Mount Drum and the Nabesna Glacier river system. Most of the cinder cones are <100 m high, but Mount Gordon is a composite basaltic cinder-lava cone 5 km in diameter and 625 m high. Many of the cones retain their original constructional forms (Richter, in Wood and Kienle, 1990). Construction of the cone was preceded by the effusion of basaltic lava flows, and airfall deposits from the cone blanket the area. The precise age of the largely ice-covered Mount Gordon cinder cone is not known.
