Mount Marcy is the highest point in New York, with an elevation of 5,344 feet. It is located in the Town of Keene in Essex County. The mountain is in the heart of the Adirondack High Peaks region of the High Peaks Wilderness Area. Its stature and expansive views make it a popular destination for hikers, who crowd its summit in the summer months.
Lake Tear of the Clouds, at the col between Mounts Marcy and Skylight is often cited as the highest source of the Hudson River, via Feldspar Brook and the Opalescent River, even though the main stem of the Opalescent River has as its source a higher point two miles north of Lake of the Clouds, and that stem is a mile longer than Feldspar Brook.
