Photo Gallery

Ixtepeque volcano is perhaps the largest obsidian field in North America. The low, forested volcano is not particularly imposing from the ground, but displays impressive arcuate flow ridges on aerial photos. Volcán Ixtepeque, which takes its name from the Aztec word for obsidian, is seen here from the west. A 4 x 5 km wide rhyolitic obsidian lava field was erupted within the Ipala graben from a craterless vent along a NE-trending fissure. Obsidian from Ixtepeque has been found at archaeological sites across Central America.
