Description of the Ascent of Koryaksky Volcano

Via the South Ridge, Category 3B difficulty

1. General description of the summit and its location. Koryakskaya Sopka is part of the Avachinsky group of volcanoes, located slightly east of the general direction of the Eastern Ridge. Among the Avachinsky group of volcanoes, Koryakskaya Sopka is the highest. Its absolute height above sea level is 3456 m. Koryaksky volcano is considered active. It last erupted in 1957. Currently, its activity is characterized by intense fumarolic activity. Steam and gas escape from a fissure crater located on the western slope, 500 m below the summit. Koryakskaya Sopka is a summit of volcanic origin. Its slopes are composed of loose volcanic rocks: basalt, tuff, and diabase. The snowline rises to a height of 2 thousand meters by August and remains there until the beginning of September. On the northern slopes, snow persists at an altitude of 1300–1600 m. The NE, NW, and N slopes of the sopka are covered with glaciers, which are cut by rocky ridges in a radial direction. At an altitude of about 3000 m, the rocky ridges disappear under the ice armor. At this height, there is a continuous conical closed glacier. Between the ridges, the glacier flows down to a height of 1100–1400 m, giving rise to several tributaries of the Nalychovo River. The western and eastern wings of the glacier end at the top of the South slope in a steep cirque. On the southern side, the foothills represent a terrain heavily dissected by ravines. The ravines run in the directions:

• from north to southeast;
• from north to south and southwest.
