Almost an island, it is the northernmost point of the North American mainland, reaching 71k58′ N, and was formerly the location of the north magnetic pole. With an area of 12,483 sq mi (32,330 sq km), it extends into the Arctic Ocean and is separated from Baffin Island by the Gulf of Boothia and from Prince of Wales Island by the Franklin Strait. It was discovered in 1829 by James Clark Ross, who named it Boothia Felix for Sir Felix Booth, the expedition's financier. It is sparsely populated.
