Ascending the summit of Klyuchevskaya Sopka from the west 2A cat. difficulty

Description

Klyuchevskoy volcano is the largest active volcano in Asia and the highest point in the RSFSR. Its height is 4750 m. The volcano has a regular conical shape with slopes of 35–40°. This volcano is still actively erupting. If you reach the summit during weak emissions from the vent, you can stay there overnight and witness an amazing spectacle. Above the crater, there is a fiery glow and fountains of sparks. The crater walls are 350–400 m high. To the north, the height decreases to 200 m. There are cracks along the entire perimeter of the crater:

• From the north, the crack reaches the bottom of the crater.
• You can enter the crater through the northern crack, but it involves certain risks. On the southern side, there is a crack with a depth of up to 25 m. On its left slope is the highest point of the summit — along the ascent route, there is a cairn with a note and an ice axe driven in. The ascent to Klyuchevskoy volcano is technically not difficult, but due to frequent and prolonged rockfalls, it requires great attention. The entire ascent must be done in teams with simultaneous belaying.

Vlk. Ovalnaya Zimina. 3081 m, 2A cat. diff., S. Grebnyu, V. Sergeev, 1965. The base camp is conveniently located under the southern slopes of Vlk. Bezymyannyy. There is a volcanologists' house here. From the camp site, the route is clearly visible (see photo). From the camp, crossing the valley, the ascent is along a wide hollow, the approach takes about an hour. Along the hollow - exit to the circus, approaching the steep ascent, the climb straight up, exit to a wide shoulder. Further ascent along the slope to the firn plateau (on the edge of the plateau - a large rocky bastion). From the plateau - ascent along the snowy slope, along a vaguely expressed lava ridge, breaking off to the east with cornices and an icefall. Along the ridge - approach to the pre-summit rocky bashnya, under it traverse - exit to the dome. The entire route is traversed simultaneously in crampons. The dome has two peaks, the southern peak is higher, between the peaks - a small depression. The ascent time takes 8-9 hours. Descent from the summit along the ascent path to the shoulder, then it is more convenient to descend along the ridge through the lateral red dome, consisting of small slag. □

1. Location description of the volcano

Ovalnaya Zimina is located in the central part of the Klyuchevskaya group of volcanoes. This is an ancient extinct volcano with gentle, uniform slopes from the north and east. Its western and southern slopes are steep and heavily destroyed. The summit of Ovalnaya Zimina is snow-ice. A 4-meter pole is installed at the highest point of the summit, clearly visible from all sides. It is impossible to blow it away by wind. A hermetically sealed metal box is nailed to this pole.

Vlk. Os­t­ry Tol­ba­chik. 3682 m through Plos­kiy from the north, 2B cat. dif., (A. Be­re­zin, 1965)

From the base camp, located in the valley of the Stu­de­na­ya river, the approach to the beginning of the ridge of Plos­kiy Tol­ba­chik along alpine meadows takes 2 hours. At the foot of the ridge begins a large and medium scree, along them along the glacier - the exit to the beginning of the ascent (see photo). The ridge is a wide lava flow, covered with firn and ice, passed simultaneously in rope teams. Before reaching the summit of Plos­kiy Tol­ba­chik volcano, the slope steepness increases to 35°, and there are many open crevasses (Bergschrunds); all crevasses are overcome by snow bridges. The summit of Plos­kiy Tol­ba­chik is a snow-firn plateau three kilometers long, with a huge crater in the western part, 1800 m by 1500 m in diameter. Along the plateau in the western direction - the exit to the edge of the crater. The ascent time for this section of Plos­kiy Tol­ba­chik volcano is 5-6 hours. Crossing the plateau in the direction of the snowy ridge, one and a half kilometers long, with a steepness of 35-40°, leads to the summit of Os­t­ry Tol­ba­chik. Passing the ridge is done simultaneously in rope teams. The ascent from Plos­kiy Tol­ba­chik to the summit of Os­t­ry Tol­ba­chik takes 1.5-2 hours. The summit is a snow dome, from which icefalls descend to the north and south. The total ascent time is 8-9 hours. Descent from the summit:

• along the ascent route;
• it is possible to descend directly from the summit along the 2B route - the northern slope.
