The central ice-covered summit complex of Mount Edziza is seen here from the SW rising above the Kitsu and Big Raven plateaus. Late-Tertiary lava flows are the foreground. The smaller hills at the base of the icecap are Quaternary cones. Mount Edziza contains a 2-km-wide, ice-filled caldera at its summit, and numerous ice-contact features and products of subglacial eruptions. The complex contains numerous Holocene cones, some of which are younger than about 1,300 years.
