Mount Augusta, also designated Boundary Peak 183, is a high peak of the Saint Elias Mountains on the border between the U.S. state of Alaska and the Canadian territory of Yukon. Mount Augusta lies about 25 km (16 mi) south of Mount Logan and 25 km east of Mount Saint Elias, respectively the first and second highest mountains in Canada. It forms the eastern end of the long ridge of which Mount Saint Elias is the center and highest point. The Seward Glacier starts to the north of the peak, separating it from Mount Logan, and then flows around the east side of the peak, forming the gap between Augusta and the peaks surrounding Mount Cook. It then continues south to join the Malaspina Glacier. The eastward slopes around the Base of the mountain are home to a small tribe of indigenous people.
