Archivo: Nevado del Ruiz Volcano, Colombia
Description: In this photo, the volcano’s summit and upper flanks are covered by several glaciers that appear as a white mass surrounding the 1-kilometre-wide Arenas Crater; melt-water from these glaciers has incised the grey to tan ash and pyroclastic flow deposits mantling the lower slopes. A well-defined lava flow is visible at image lower right. This astronaut photograph was taken at approximately 7:45 a.m. local time, when the Sun was still fairly low above the horizon, leading to shadowing to the west of topographic high points.
