It is a National Wildlife Refuge under the USFWS and public access is by permit only; permits are usually issued for scientists and educators. The atoll was discovered when the American brig Sally ran aground in 1796. The largest island was named Johnston Island for the captain of the frigate HMS Cornwallis from which the island was sighted in 1807.
