Gavriil Pribylov discovers St. George Island of the Pribilof Islands in the Bering Sea.

Gavriil Loginovich Pribylov was a Russian navigator who discovered the Bering Sea islands of St. George Island and St. Paul Island in 1786 and 1787. The islands, and surrounding small islets, now bear his name, being known as the Pribilof Islands.

St. George is a city in Aleutians West Census Area, Alaska, United States. It is the main settlement of St. George Island in the Pribilofs, a small island group in the Bering Sea. As of the 2020 census, the population was 67, down from 102 in 2010 and the lowest figure since records began in 1880.

The Pribilof Islands are a group of four volcanic islands off the coast of mainland Alaska, in the Bering Sea, about 200 miles (320 km) north of Unalaska and 200 miles (320 km) southwest of Cape Newenham. The islands are part of the Alaska Maritime National Wildlife Refuge. The Siberian coast is roughly 500 miles (800 km) northwest. About 77 square miles (200 km²) in total area, they are mostly rocky and are covered with tundra, with a population of 572 as of the 2010 census.

The Bering Sea is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and the Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. The Bering Sea is named after Vitus Bering, a Danish-born Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean.
