The summit of Cosigüina volcano, seen here from the west with the Gulf of Fonseca in the background and the border with Honduras at the upper left, contains a 2 x 2.4 km wide caldera with steep-sided, 500-m-high walls. The upper flanks of the volcano are only partially forested after a devastating eruption in 1835 produced pyroclastic flows and surges that reached the coast and fountain-fed lava flows that blanketed the upper eastern and western flanks. The peak in the distance below the right side of the wing is San Cristóbal volcano.
