The upper climb gets steeper and thinner on trees. After the main creek crossings, a long set of switchbacks carries the trail toward 10,000 feet and above. Recent reports describe the last mile and a half as harder to follow than the lower trail, so pay attention to the main tread, especially where smaller paths appear. Near the lake, a steep, rocky route climbs toward a saddle and Johnson Lake. For Baker Lake, continue straight to the shore; that Johnson Lake extension is a separate, longer route, not part of this out-and-back.
