This volcano is located about 2700 km (1600 mi) southeast of Elysium Mons near the boundary between the densely cratered plains of the northern hemisphere. The southern flank is covered by a radiating fan of lava flows emanating from a breach in the southeastern rim of the caldera. Different episodes of caldera flooding are preserved as floor segments within the caldera. The lowest caldera floor is probably contemporaneous with the lava flows covering the southern flank.
