Misti is a volcano in the southern Peruvian Andes, rising above Arequipa, Peru’s second-largest city. It has a steep conical profile and two nested summit craters. The inner crater contains an active lava plug or dome, pierced by vents that emit volcanic gases. The summit reaches 5822 m above sea level, on the rim of the outer crater. Snow covers the summit but does not persist, and there are no glaciers. The upper slopes are largely barren, while lower elevations support scrub and other bushy vegetation.
