A drive through the northern part of the Delaware Water Gap National Recreation area might lead you through the oldest municipality in Sussex County. There is a Post Office, there is a church, and there is a school, or at least what looks like was once a school. There are a few houses that line a street unlike any other in the area, with their painted white exteriors, red brick chimneys, and small shady porches. There is absolutely no one to talk to. A few miles from Buttermilk Falls in the Delaware Water Gap National Recreation Area, in the Flat Brook Valley, stands Wallpack Center, the town that time forgot!
