Phase three down the Erie Canal. The Erie Canal rises 566 feet from the Hudson River to Lake Erie through 57 locks. From tide-water level at Troy, the Erie Canal rises through a series of locks in the Mohawk Valley to an elevation of 420 feet above sea-level at the summit level at Rome. Continuing westward, it descends to an elevation of 363 feet above sea-level at the junction with the Oswego Canal, and finally rises to an elevation of 565.6 feet above sea-level at the Niagara River. These are the final 5 days of our journey!!
