Over 7,000 sq mi (18,100 sq km) of the disputed area, including the Aroostook valley, were given to the United States, and several waterways, including the St. Johns River, were opened to free navigation by both countries. The Webster-Ashburton Treaty also settled the disputed position of the U.S.-Canada border in the Great Lakes region. Other clauses provided for cooperation in the suppression of the slave trade and for mutual extradition of criminals.
