Ascend adjacent to the streambed; you can see that there is a climber's trail for much of the way. Above the snowbank shaped like South America, angle right as you continue up and aim for the cliffs just right of the "knob" just right of center. There, climb weaknesses in the cliffs or use a scree-covered ledge that deposits you a short distance east of the summit. Climbing the cliffs' weaknesses gets you even closer to the summit, about a 30-second walk away.
This route can be as short as 1.2-1.3 mi, but it is very steep, gaining a little over 3000' during its course.
