The Three Sisters are a group of Volcanos in the Central Oregon Cascades. They are a prominent feature of Central Oregon along with Mt. Bachelor and Broken Top. The South Sister is the largest, tallest, and youngest of the three. At 10,358 ft the South Sister is the third tallest mountain in Oregon. Climbing the South Sister is a non-technical hike to the summit. It is probably the easiest climb of any of the major Oregon Cascade volcanos. It requires a fair amount of stamina, a high tolerance for scree, and most of a day. The Devil's Lake route is over 12 miles long and features an elevation gain of over 5000 feet. I climbed it October 3, 2009, we had perfect weather and it was before the first snows of the season. The first photo is of the approach about 2 miles from the trailhead. The second photo is looking up at the summit from the base of the Lewis Glacier at about 8800 feet. The third photo is of the summit crater. The fourth photo is the view to the north from the summit, you can see the Middle Sister, North Sister, Three Finger Jack, Mt. Jefferson, and Mt. Hood. The last photo the view to the southwest, you can see a lava field and it is hazy in the south because of forest fires.
