The Adirondack Mountains in northeastern New York form a massive circular dome of mountains that is geologically distinct from the nearby Appalachians. Part of the Canadian Shield, the range consists of ancient rocks over a billion years old that have been uplifted in a relatively recent geological dome formation. The mountains are the centerpiece of Adirondack Park, the largest state-protected area in the contiguous United States, covering an area larger than several New England states combined. Famous for the "46 High Peaks," the region features a pristine wilderness with thousands of lakes, ponds, and miles of wild rivers set amidst dense forests. Historically, the Adirondacks were a foundational site for the American conservation movement and saw the development of the unique "Adirondack style" in architecture. Today, the range is a year-round destination for outdoor activities, including winter sports in Lake Placid, which has twice hosted the Winter Olympics.
