Ichinsky volcano is the largest volcanic structure of the Sredinny Range of Kamchatka. The manifestation of fumarole activity on the northern slope of the volcano is known since 1956. 64 years after the discovery of the Ledovaya fumarole, it was inspected with a quadrocopter. It was found that the fumarole is located at an altitude of 2725 m and is a large funnel up to 60 m in size, covered with snow in the middle part. In the upper part of the funnel there is a hole in the ice mass 9.8 m in diameter, with vapor-gas clouds rising up to 5–10 m above its edge. The walls of the ice well are covered with a grayish-yellow fouling of sublimations. The authors believe that the probable temperature of the vapor-gas mixture of fumaroles at the outlet of the volcano rocks is significantly higher than 100° C.
