The upper flanks of the dominantly Pleistocene Nevado de Toluca volcano consist primarily of lava flows that are well exposed above the tree line. This view shows the western flanks of Pico del Fraile, the high point on the SW rim of the horseshoe-shaped summit crater. The summit crater and flanks have been extensively modified by glacial erosion.
