This mountainous land has the convergence of the Alaska, Chugach, and Wrangell-Saint Elias Ranges, which have many of the continent's tallest mountains over 16,000 feet (4,900�m), including Mount Saint Elias. More than 25% of this park of volcanic peaks is covered with glaciers, including the tidewater Hubbard Glacier, piedmont Malaspina Glacier, and valley Nabesna Glacier.
