Baidzharakhi – (derived from a Yakut word) a hammock rising over the ground due to the process of fossil ice melting out in the regions of permafrost prevalence. Usually can be found in groups and are arranged in rows. B’s diameter is 3–10 m; its height ranges from 0.5 to 5 m. They are separated from each other by ravines. On the smooth slopes of rivers and brook valleys, there can be seen some outlines of hillocks no higher than 0.5 m. On the steep slopes B. are of a conical shape and rise up to 1.5–3 m high. On the slopes of hollows and in the upper reaches of brooks, Bs form the so-called baidzharakhi circuses which sometimes occupy a large territory. On the New Siberian Islands, they cover vast areas. Bs are characteristic of Northeastern Asia and Alaska.
