Photographs of the Summit Region
A) View of the Santa Maria cone (looking east) from Quebrada Agria ridge in the dead zone. The peak of Miravalles volcano, the next volcano southeast of Rincon de la Vieja, can be seen just left and in back of Santa Maria. The Santa Maria cone is completely vegetated and appears to have been dormant for several thousand years.
B) View looking north over the rim of the Active Crater. The Active Crater contains a highly acidic lake with a measured pH of 0.0 (yes, zero!). During many of the historical eruptions, large volumes of the lake have been expelled, forming acidic lahars that rapidly descend down northward drainages.
C) View from the Von Seebach cone looking east at the Active Crater and the vegetated cone, Rincon de la Vieja.
