The western side of the low-angle, eroded Ixhuatán volcanic complex rises beyond the Río Los Esclavos as seen from the flank of Tecuamburro volcano. The 1718-m-high dominantly andesitic volcano is of Pliocene-Pleistocene age. The youngest center is a dacitic lava-dome complex at Cerro los Achiotes. The domes and associated ashfall and ashflow deposits partially fill and extend from a horseshoe-shaped caldera that is breached to the SE and may have formed as a result of slope failure.
