What is the water depth of sanctuary which is the site of the wreck of the first ironclad warship commissioned by the union navy?
Monitor National Marine Sanctuary Monitor National Marine Sanctuary is the site of the wreck of the USS "Monitor", one of the most famous shipwrecks in U.S. history. It was designated as the country's first national marine sanctuary on January 30, 1975, and is one of only two of the thirteen national marine sanctuaries created to protect a cultural resource rather than a natural resource. The sanctuary comprises a column of water 1 nmi in diameter extending from the ocean’s surface to the seabed around the wreck of the Civil War ironclad, which lies 16 nmi south-southeast of Cape Hatteras, North Carolina. Average water depth in the sanctuary is 230 ft . Since its sinking in 1862, the "Monitor" has become an artificial reef attracting numerous fish species, including amberjack, black seabass, oyster toadfish and great barracuda.
USS Mahaska (1861) The first USS "Mahaska" was a wooden, double-ender, sidewheel steamer of the third rate in the United States Navy during the American Civil War. She was named for Ioway Chief Mahaska.
