Midway Atoll comprises three coral islands and 580,000 acres of submerged reef and ocean at the far northern end of the Hawaiian archipelago. From left to right, the islands are Sand Island, tiny Spit Island and Eastern Island. They total about 1,549 acres. An atoll is a ring-shaped coral reef or a compact string of coral islets that at least partially enclose a shallow lagoon.
