The Monte da Guia tuff cone forms a backdrop to the harbor of Horta, the largest town on the island of Fayal. The cone was formed by phreatomagmatic eruptions just off the SE tip of the island and is now connected to Fayal by a low narrow peninsula. It is one of a cluster of cones on the lower SE flank. These cones and an associated basaltic lava field form the late Pleistocene Almoxarife Formation. Photo by Rick Wunderman, 1997 (Smithsonian Institution).
