River of Mountains: A Canoe Journey down the Hudson

Lourie completed his trip. It took him three weeks and marked the first time anyone has traveled from the source of the Hudson to the mouth in a single vessel. The Hudson proved to be a very changeable river. It includes seven locks and nine power dams. The northern half is a true river with strong current, but the lower half is tidal, a sunken river from the days of glaciers. In its first 165 miles, it drops more than 4,000 feet to Albany. The second half falls no more than a foot.
