| Description: | This area is located very near the highest point on horn Veleta Peak (3,398 m) and its base is formed by Corral del Veleta glacier cirque. Corral del Veleta is located at the extreme western end of Sierra Nevada (37º 03’ 24’’ N and 3º 22’ 05’’ W) in the Cryomediterranean bioclimatic zone, and has the particularity of being the most southern work site in Europe. Topographically, Corral is an oval-shaped bowl with a NE orientation, that opens out into the Guarnón Valley. Steep vertical walls (more than 300 m elevation gain) surround the bowl. The highest point on the wall adjoins Picacho del Veleta (3,398 m) and Cerro de Los Machos (3,374 m). The floor of Corral is located at an average altitude of 3020 m and stretches 600 m from east to west and 250-175 m from north to south. The base of the cirque is at an average altitude of 3020 m and joins a ledge-like structure upon which various morainic formations are visible. Between the tardiglacial period and the Little Ice Age, a series of morainic ridges and other detrital deposits with diverse morphogenesis, in-filled the interior of the cirque. These ridges now overlap each other and are marred by snow hollows and incipient rock-glaciers and ice-creep features. Some of the ridges resemble lateral deposits that form parallel to the glacier flow while others are similar to terminal deposits and consist of debris from the rock falls and avalanches that originate on the sidewalls. |
