Wrangel Island
During the last ice age, woolly mammoths ("Mammuthus primigenius") lived on Wrangel Island in the Arctic Ocean and survived until 1700 BC, the most recent survival of any known mammoth population. Wrangel Island is thought to have become separated from the mainland by 12000 BC. It was assumed that Wrangel Island mammoths ranged from 180–230 cm in shoulder height and were for a time considered "dwarf mammoths". However this classification has been re-evaluated and since the Second International Mammoth Conference in 1999, these mammoths are no longer considered to be true "dwarf mammoths".
