White-colored pyroclastic-flow and -fall deposits from Ilopango caldera known collectively as Tierra Blanca (White Soil) blanket much of central and western El Salvador.  This quarry near the city of Cojutepeque, 9 km ENE of the caldera, exposes the Tierra Blanca Joven (TBJ) formation, produced during the youngest of the several Tierra Blanca eruptions about 1500 years ago. The eruption destroyed early Mayan cities and forced their abandonment for decades to centuries.   Photo by Giuseppina Kysar, 1999 (Smithsonian Institution).
