The Olyutorsky Bay (Russian: Олюторский залив) is a gulf or bay of the Bering Sea in the northern part of Kamchatka Krai, Russia. It is bounded on the west by the Govena Peninsula which separates it from Korfa Bay and on the east by the Olyutorsky Peninsula. It extends roughly 83 km inland and is 228 km at its widest. The deepest spot is about 1,000 meters. The western shore is dominated by the Pylginsky Ridge, which has a maximum elevation of 1,357 meters. The bay is normally covered by fast ice from December to May. It has a large tidal range of up to 1.9 meters.
The Olyutorsky District is one of the four districts of the Koryak Okrug. The Alyutors, a branch of the Koryaks lived in the area or somewhat west. There were also Yukagirs, some of whom had been brought south by the Russians. The major rivers are the Pakhacha and the Apuka. Their headwaters are close to the north-flowing Mayn River, and Velikaya River (Chukotka), branches of the Anadyr River. Lantzeff [1] speaks of an Oliutora River, which does not appear on modern maps and which he distinguishes from the Pakhacha. In 1714 the Russians built the ostrog of Oliutorsk to control the coast and land route from Kamchatka to Anadyrsk, a function it shared with Aklansk. It was besieged by the Yukagirs and Koryaks. It lost its importance after the sea route from Okhotsk was opened.
