The Three Sisters are a complex volcano of three volcanic peaks of the Cascade Volcanic Arc and the Cascade Range in the U.S. state of Oregon. Each exceeding 10,000 feet (3,000 m) in elevation, they are the third, fourth, and fifth highest peaks in the state of Oregon, and are located in the Three Sisters Wilderness, about 10 miles (16 km) south of the nearest town of Sisters. Diverse species of flora and fauna inhabit the area on and around the mountains, which is subject to frequent snowfall, occasional rain, and extreme temperature differences between seasons. The mountains, particularly South Sister, are popular for climbing and scrambling. Although they are often grouped together and seen as one unit, the three mountains evolved under differing geologic situations, and the petrologic composition of each mountain can vary significantly. Whereas North Sister is extinct and Middle Sister is inactive, South Sister last erupted about 2,000 years ago and still could erupt, threatening life within the region. After satellite imagery detected uplift near South Sister in 2000, the United States Geological Survey made plans to improve monitoring in the immediate area. The Three Sisters are located on the boundaries of Lane and Deschutes counties and the Willamette and Deschutes national forests in the U.S. state of Oregon, about 10 miles (16 km) south of the nearest town of Sisters. The three peaks, the third, fourth, and fifth highest peaks in Oregon, have 15 named glaciers among them, nearly half of the 35 named glaciers in Oregon. The Sisters were named Faith, Hope, and Charity by early settlers, but "these names have not prevailed", and instead they are named North Sister, Middle Sister, and South Sister.
