In 1969 the United States Army Corps of Engineers built a coffer dam and redirected the entire Niagara River away from the American Falls. The cliff stood completely dry for five months. The exposed river bed revealed centuries of hidden objects — including the remains of two people. Geological surveys revealed the cliff was cracking and without intervention the falls would have collapsed within decades. The full report of findings was never publicly released. Every fact in this documentary is historically documented.
