The SW flank of Rincón de la Vieja volcano contains an unusual broad triangular area almost entirely devoid of vegetation.  This so-called "dead zone" has resulted from active eruptions and volcanically derived acid rain.  Steady trade winds from the NNE distribute acidic vapors rising from Active Crater to the SW.  These factors have created unusual exposures revealing the stratigraphy of the volcano. Photo by William Melson, 1986 (Smithsonian Institution).
