Geological summary
A solitary, 1-km-wide, lake-filled maar, Laguna Aramuaca, occupies a low-lying area about 10 km SE of the city of San Miguel. The Pan-American highway swings around the S side of the maar, immediately N of the Río Grande de San Miguel. It was mapped as Holocene by Weber and Wiesemann (1978), but has not been studied in detail. The low rim of the maar rises above the countryside but is only slightly above sea level; spectacular pyroclastic-surge deposits are exposed by quarries near the rim.
