The summit depression of Tequila volcano is breached narrowly to the NE and originated from erosional excavation.  A prominent 300-m-high dacitic spine, left after erosional removal of softer rocks surrounding the vent, forms the dramatic steep-sided peak at the left.  The spine was dated at about 210,000 years and probably represents the latest activity from the central vent.   Photo by Jim Luhr, 1979 (Smithsonian Institution).
