Kolesovsky Island is 3 km long. This island is only 0.7 km across and it is located 4 km to the northwest of Kolesovskaya Otmel, very close to a coastal headland.[1]
Kolyma Bay, where the Kolesovsky Island lies, 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. The area surrounding Kolesovsky Island comes to life during the summer when there is commercial fishing in the surrounding waters.[2]
