The Hudson River in New York state extends about 300 miles (483 kilometers) from Lake Tear-of-the-Clouds on Mount Marcy down to New York Bay. When people think of the Hudson, what comes to mind is the part of the river that flows through the New York metropolitan area. This section does not freeze often, the last time being in January of 1918. However, at the higher elevations near the river’s source, the Hudson freezes quite regularly.
