Mud Flow

Figure 25
[67]  As has been noted above, after the termination of the ice avalanche in the Skalistyi Range escarpment, the catastrophic process continued in the form of an ice-rock mud flow, 30-40 m high. Moving at a speed of more than 100 km/hour, this deadly hurricane crossed the distance of 5.5 km in the Genaldon Canyon (Figure 16). Most of the victims were restricted to this band ranging from 30 m to 80 m in width. The mud flow material covered an area of 3 km2. Its thickness declined in the direction away from the ice barrier, where it is as high as 11 m, to 4 m at the exit from the canyon, and to 2 m at the junction of the Genaldon and Gizeldon rivers (Figure 25). The volume of the mud flow material has been estimated as 3-5 million m3.

[68]  By the present time, at the lower stages of the mud flow, the Gizeldon R. flow returns to the initial basis of the bottom erosion with the formation of terraces, the vegetation winning back its lost territories. New roads and bridges are being built in the segments of the demolished roads. No road is planned to be built along the canyon.
