The Mill Chute was a ride at Hersheypark from 1929 until 1972. Milton S. Hershey purchased the ride from the Philadelphia Toboggan Company when the decision was made to build a new pool and drain the existing pool and neighboring lake in Comet Hollow. In 1963, the ride was renovated and rethemed. It was renamed Lost River and maintained that theme until 1972. During the 1972 season Hurricane Agnes struck Hershey, and the resulting flood of the park caused irreparable damage to the ride. As a result, the ride was closed for the remainder of the 1972 season and was torn down in the off season.
