A steam plume rises from Active Crater (Cráter Activo) of Rincón de la Vieja, seen here from the south. An acid crater lake fills the innermost of two nested craters of the historically active pyroclastic cone. Frequent historical eruptions and the production of acid rain have kept the flanks of the cone unvegetated. Remobilization of fresh ashfall deposits has led to mudflows down the Quebrada Azufrosa at the upper right.
