Lyakhovskiy Islands – a southern group in the archipelago of the New Siberian Islands dividing the Laptev and East Siberian seas. They consist of the Great Lyakhovskiy (area of approx. 4,600 km2), Small Lyakhovskiy (area of 1,325 km2), and Stolbovoy (area of approx. 170 km2) islands. The total area is 6,600 km2. From the Asian continent, the islands are separated by the Dmitriy Laptev Strait. Most of the islands are composed of surface sand and clay deposits covering fossil ice. The islands are covered with tundra vegetation. Polar foxes are commercially exploited species. The islands were discovered in 1712 by Cossack Merkuriy Vagin. L.I. were named by the decree of Catherine II in honor of the Yakut merchant and industrialist I. Lyakhov, who had visited the islands for the first time for fishing and hunting purposes in 1770.
