Guazapa
"Guazapa is a massive, eroded Pleistocene stratovolcano that rises 1000 m above the surrounding countryside NE of the capital city of San Salvador. The 1438-m-high basaltic volcano has no trace of its original summit crater, and deep canyons cut its flanks. Several young Holocene pyroclastic cones and lava flows of similar composition are found at the base of the volcano (Williams and Meyer-Abich, 1955). The Macanze scoria cone at the SE base of the volcano was considered to have probably been active only a few thousand years ago, however Weber and Wiesemann (1978) did not map Holocene vents in this area."  -Smithsonian Volcano Archive
