The article presents facts about penitentes, pinnacles that form during the dry Andean summers on high-altitude glaciers. The formation occurs through a self-amplification process of oblation by direct and reflected radiation. The depressions produced by sublimation on the surface of a glacier can leave peaks reaching one to four meters high. Dirt and debris affect penitente formation. |
