Damage from Superstorm Sandy was not limited to heavily populated cities along the Eastern Seaboard. Up and down the East Coast and farther inland, heavy winds, tidal surge, rain and snow caused significant damage to national parks. As of Tuesday night, 69 parks were either closed or partially cordoned off because of the storm, according to the National Park Service, a bureau of the Department of Interior. More than 100 park employees were being deployed to the hardest hit areas, with a focus on northern New Jersey and harbor parks in New York City.
