Adirondack Mountains, Mountain range in northeastern New York, United States
The Adirondack Mountains form a circular dome in northeastern New York, stretching roughly 160 miles and containing more than 100 peaks. Mount Marcy rises as the highest point at 5344 feet (1628 meters).
This range formed roughly two billion years ago during the Grenville mountain-building period, when ancient sea sediments transformed into metamorphic rock. After the last ice age, indigenous peoples settled the area and developed seasonal hunting and fishing patterns.
Local families return to the same trails and campsites every summer, often gathering around evening fires by the lakeshores. Small towns around the edges of the range host traditional craft fairs and sell locally made maple products and woodwork.
More than 2000 miles of marked trails cross the area, offering routes for beginners and experienced climbers alike. Over 3000 lakes and numerous rivers allow for canoeing, fishing, and swimming from spring through fall.
Lake Tear of the Clouds sits at 4292 feet (1308 meters) and marks the source of the Hudson River. This small alpine lake feeds one of the longest rivers on the East Coast.
