The Sentinel Range is a prominent mountain range located in the Antarctic region, specifically within the Ellsworth Mountains. It stretches approximately 60 miles (97 kilometers) and is known for its rugged terrain and high peaks, including the tallest peak, Mount Vinson, which rises to 16,050 feet (4,892 meters). The range is primarily composed of granite and is covered by glaciers. This range is significant for scientific research, particularly in the fields of geology and climate studies. The Sentinel Range is also home to various species of wildlife, including seals and penguins, which thrive in the surrounding icy environment.
