Celebrate our nation’s birth with a hike along Patriots’ Path to the archaeological site of Jacob Ford Jr.’s Powder Mill. A visit to the archaeological site of the oldest remaining Revolutionary-Era powder mill site located along the Whippany River will offer insight into how a small wooden structure with a dirt/rock-lined floor was crucial in our fight for independence.

Recent research has shown evidence that the mill was used for the critical remanufacture of damaged gun powder. The remanufactured powder was then disbursed to troops in the field and to Gen. Henry Knox’s cantonment near Pluckemin.

Visitors will meet at 11 a.m. at Acorn Hall and walk about one-quarter of a mile to the site of the mill and return. The hour-long event is free.
