Lone Eagle Peak
This was to be an extra side trip from Crater Lake, being only 1.2 miles
from the eastern shore of the lake. This trail is much more involved than the hike to Crater Lake, and requires about 1,200 feet of elevation gain over the distance. 
Starting from the trail going to Crater Lake, just before you reach the lake, there is a faint trail that swerves off to the left. This is the trail up Lone Eagle. The trail is very faint, but stay south until you reach the eastern shore of the lake. From here you must scramble up the boulders that lie in front of you up to the ridge separating the west and east faces of the peak. Scramble up to this saddle and face what lies before you. The easiest going from this point is right under the cliffs of the peak. We continued up the side of the peak until we can to a point where we couldn't climb any farther. From here, we scrambled down about 50 feet onto the wide ledge that continues up the east side. Assessing our energy and the time, plus the changing weather, we determined that it would best be done another day. Some friendly advice to all those hoping to do this climb in one day: it can be done, but start early so as to get off the summit by noon. Weather in this part of the state changes rapidly, as it did in our case. Just the hike to Crater Lake is a great day hike, and the views of the peak and the glacier contained within are fabulous. 
I would highly recommend this climb to anyone with some experience. The exposure increases rapidly from Crater Lake and it becomes increasingly difficult climbing along the ridge. One interesting feature about this climb that I am aware of, the ridge to the summit is actually downclimbing and traversing. Another thing to make known is that Lone Eagle is NOT the high point on the ridge, but the closest summit to Crater Lake.
