Herald Island (Arctic)

Herald Island (Russian: Остров Геральд, Ostrov Gerald) is a small, isolated Russian island in the Chukchi Sea, 70 km (43 mi) to the east of Wrangel Island. It rises in sheer cliffs, making it quite inaccessible, either by ship or by plane. The only sliver of accessible shoreline is at its northwestern point, where the cliffs have crumbled into piles of loose rocks and gravel. Its area is 11.3 km2 (4.36 sq mi) and the maximum height above sea level is 364 m (1,194 ft). The island is unglaciated and uninhabited. The island is named for the survey vessel HMS Herald, from which the island was discovered in 1849.

Herald Island belongs administratively to the Chukotka Autonomous Okrug of the Russian Federation. Along with Wrangel Island, Herald Island is part of the Wrangel Island Wildlife Preserve, a Russian National Park, since 1976. Cape Dmitrieva in Herald Island, marks the easternmost limits of the nature reserve.
