Aello Peak

Aello Peak is the highest peak of a mountain group called The Twaharpies, just west of Mount Bona in the Saint Elias Mountains of Alaska. While not highly significant in terms of prominence or isolation (it is just 5 miles (8 km) west of the summit of Mount Bona), it has a tremendous south face. From the summit, this face drops 7,000 feet (2,130 m) in just over 1 mile (1.6 km), and 8,500 feet (2,590 m) in less than 2.5 miles (4.0 km). In terms of vertical relief and steepness, this is one of the major faces in North America.
