The flat light-colored area at the top of the photo beyond Las Pilas volcano in the foreground is the Malpaisillo caldera. This large but topographically indistinct pyroclastic shield volcano lies in the Nicaraguan depression NE of Las Pilas volcano and NNW of Momotombo volcano. Formation of the 10-km-wide Malpaisillo caldera produced extensively dissected dacitic airfall and ignimbrite deposits that extend across the graben east of the Marrabios Range and reach into Lake Managua to the SE.
