North Tulsa is home to a large percentage of Tulsa's African-American community. The area's Booker T. Washington High School, Tulsa’s African-American high school during the segregation era and now a magnet school, was recently judged to be the 58th best high school in the nation by Newsweek. Northwest of downtown on the Osage Indian Reservation is the Gilcrease Museum, considered by many to be the finest Western American and American Indian art collection in the world. Northeast of downtown, close to Tulsa International Airport, are Mohawk Park, which includes the Tulsa Zoo and the Oxley Nature Center, and the new Tulsa Air and Space Center and Planetarium. This area is also home to the American Airlines maintenance facility, one of Tulsa's largest employers.
