It is located close to the coast in the Kolyma Bay (Kolymskaya Guba), south of the Konechnaya Channel and 13 km east of the mouths of the Indigirka River.
[1] In satellite pictures it appears as two separate islands, a large one at the northern end and a small one at the southern tip.
The Kolyma Bay where the Kolesovskaya Otmel lie is a desolate place in the long winters, when it remains frozen to depths of several metres for about 250 days each year.
It becomes free of ice only in early June and the thaw lasts typically until October.
