History and architectural features
The guard lock was built in 1831, and the remains consist of two ninety-foot-long parallel walls that were eight feet high and fifteen feet apart. The remains of the feeder dam consist of stone and earth remnants of a dam that once stretched across the Juniata River. The lock and dam were built to allow boats built on Standing Stone Creek to enter the Pennsylvania Canal, and were abandoned with the remainder of the Pennsylvania Canal during the 1870s.
