Cerro la Torta, the flat-topped ridge on the horizon, is a Holocene dacitic lava dome on the western side of Cerros de Tocorpuri volcano. Because of its distinctive shape, the dome is referred to locally by the Spanish word for cake (torta). Cerro la Torta, seen here from the west, is a roughly 5 cu km circular dome with a flat surface wrinkled by flow ridges and steep, 150-m-high talus-covered flanks. Emplacement of the 5090-m-high dome began with minor explosive activity, but slow lava extrusion was dominant.
