The steep remnant at Sangangüey volcano (center) rises 250 m above the Arroyo Caracol, an erosional valley down the SW flank. It is similar in composition to surrounding layered lava flows, but contains less glass, which suggests slower cooling. The Arroyo Caracol exposes a 700-m-thick section showing the interior stratigraphy of the cone.
