Description of the ascent to the "Tooth" of Kozel'skiy volcano via the Western ridge, category 2A difficulty.

1. General description of the summit and its location.

Kozel'skaya sopka is part of the Avachinskaya group of volcanoes, located in the eastern part of the Kekhur ridge. The absolute height of Kozel'skaya sopka above sea level is 2210 m. It is an extinct volcano. Its slopes are composed of basalt and diabase. The slopes are generally gentle and mostly covered with a thick layer of slag. In the summer months, the pre-summit ridge is cleared of snow, exposing several gendarmes. However, snow persists on the slopes, even on the southern ones, throughout the summer. The northern slopes of the sopka are the walls of a large ancient crater, covered with ice and firn. These walls are densely strewn with basaltic "rock fingers". The volcano has three peaks:

• Western,
• Central,
• Eastern. The highest peak is the Eastern one, which is a rocky "tooth" rising 50 m above the general massif. The walls of the "tooth" are sheer on all sides. There is a non-wall passage along the south-eastern ridge (category 1B difficulty route). A glacier is located on the western side of the sopka (the glacier serves as a boundary between Avachinskiy and Kozel'skiy volcanoes), from which the Kozel'skiy stream flows. The foot of the volcano is heavily dissected by ravines. On the eastern side of the foot, there are quarries of construction organizations developing slag.
