Description and History: The Powder Mill Valley Monument, erected in 1947 by the Haverford Township Historical Society, memorializes the early mill history of this secluded creek valley. Before the advent of steam-driven power, creeks and rivers were an important source of water power and became early industrial sites. Usually a dam was built to create a drop in water height, then some of the captured water was channeled through a “race” to drive a water wheel, which in turn mechanically drove milling, sawing or other early machinery. This area contained a number of mill establishments which were readapted to varying purposes over their existence.
