Where is the Gerry E. Studds Stellwagen Bank National Marine Sanctuary?
The sanctuary is an 842-square-mile (638-square-nautical-mile) marine protected area at the mouth of Massachusetts Bay. The sanctuary boundary is somewhat rectangular, stretching from three miles southeast of Cape Ann to three miles north of Cape Cod. The sanctuary is about 25 miles east of Boston, and lies totally within federal waters. It encompasses all of Stellwagen and Tillies Banks, and the southern portion of Jeffreys Ledge.
