The South Sister is one of three mountains in the Three Sisters Wilderness area. Each mountain is over 10,000 feet tall. At 10,358 ft (3,157 m), South Sister is the youngest and tallest volcano of the trio. It is a stratovolcano which last erupted about 1600 years ago. It has an uneroded summit crater about 0.25 mi (0.4 km) in diameter, which holds a small crater lake known as Teardrop Pool which is usually frozen except during the summer. This is the highest lake in Oregon. The standard climbing route up the South Ridge of South Sister is a long, steep, non-technical hike that can be easily completed in a day by reasonably fit hikers. Popular starting points are the Green Lakes or Devil's Lake trailheads.
In September of 2005, scientists discovered a rising bulge about three miles southwest of the South Sister. The ground in a 100 square-mile area is rising at a rate of 1.4 inches per year. Scientists believe that a lake of fluid (likely magma), 1 mile across and 65 feet deep has formed at a depth of 4.5 miles below the unpopulated area. The pooling fluid could be shifting magma or the creation of a new volcano.

Beautiful! I really love the colors, and how well you were able to capture the highlights and shadows.
It has been far too long since I have been near the Sisters.. When I was a kid my dad took me hiking up on Three Fingered Jack. I think we must have been insane because we hiked in the snow wearing shorts, then when we got to a lake my brother and I jumped in!
Thanks for sharing this beautiful photo, and for triggering some great memories!
We are both equally crazy. I used to walk to school wearing shorts and a t-shirt in 3 feet of snow. I wish I was in the physical condition to go hiking because my dad usually hikes the South Sister every year and I would love to go with him sometime.
