Litke Strait (Russian: Пролив Литке, Proliv Litke) is a strait in the Karaginsky Gulf in the Bering Sea, located off the northeastern coast of the Kamchatka Peninsula, in Kamchatka Krai of the Russian Far East. It separates the Karaginsky Island from the peninsula's mainland.
The strait is named after explorer Fyodor Petrovich Litke.
Karaginsky Gulf (Russian: Карагинский залив) is a large gulf in the Bering Sea off the northeastern coast of Kamchatka (Russia), which cuts 117 km (73 mi) deep inland. The depth of the gulf is between 30 and 60 m (98 and 197 ft). The largest island in the gulf is the Karaginsky Island, separated from the mainland by the Litke Strait (width: 21 to 72 km (13 to 45 mi)). The Karaginsky Gulf is covered with ice from December until June.
Karaginsky Island or Karaginskiy Island (Russian: Карагинский остров) is an island in the Karaginsky Gulf of the Bering Sea. The 40-kilometre (25 mi)-wide strait between the Kamchatka Peninsula and this island is called Litke Strait. Karaginsky Island is a Ramsar site. Even though the island is uninhabited, the Karagin Koryaks have traditionally lived in Karaginskiy Island. Migrant reindeer herders still live in temporary shelters on the island.
The island is 101 km (63 mi) long and up to 27 km (17 mi) wide, with an area of 193,597 ha (1,935.97 km; 747.48 sq mi). The highest peak of the island is 912 m (2,992 ft). Karaginsky Island is covered with tundra vegetation and cedar underwood. In the summer, there are many flowers.
