There is an explanatory marker (pictured above) with an illustration and map, and the following text:
"You are standing on a rocky outcrop that was a strategic lookout for General George Washington during the Revolutionary War. At that time, the land was mostly field and meadow offering a clear view for 30 miles. In June of 1888, the ability to monitor British troop movements from this location proved crucial to the survival of the Continental Army
"In the spring of 1777, over 8,000 Continental troops were camped in the Watchung Mountains - 3 miles to your right. The high elevation and mountainous terrain provided good defensive cover for Washington’s army. Despite several attempts by British General Howe to entice them down onto level ground to fight, General Washington refused to move from his secure mountain stronghold. Frustrated that his tactics had failed, Howe moved his troops to Perth Amboy and then to Staten Island . The following day, observing that the coast was clear, Washington sent a contingent of men down to Quibbletown (now the New Market section of Plainfield).
"Hearing of Washington’s movements, Howe recalled his troops and organized and led a division to attack Quibbletown. General Cornwallis took another British division to circle behind the Continentals and cut off their retreat route to the mountains. Watching these maneuvers from this lookout and realizing what the British were attempting, Washington ordered his troops to return immediately and refortify their mountain positions. This action assuredly saved the Continental Army from a disastrous defeat." [1]
