Mount Marcy
Mount Marcy is the highest point in New York State, with an elevation of 5,343 feet (1,629 m). 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 Mt. Marcy and Mt. 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.
History
The mountain is named for Gov. William L. Marcy, the 19th-century Governor of New York, who authorized the environmental survey that explored the area. Its first recorded ascent was on August 5, 1837, by a large party led by Ebenezer Emmons looking for source of the East Fork of the Hudson River. Today the summit may be reached by multiple trails; though long by any route, a round-trip may be made in a day.
