Activity Notes

South Sister is Oregon's third-tallest mountain @ 10,358-foot. The climb, 4900 ft elevation gain in 4.9 miles one way. In June the trail will be snow covered unlike later in the summer when it is just a trail, so we will need mountaineering boots, crampons & ice ax's. Depending on the conditions we might get a short glissade as well. This is a beautiful mountain with spectacular views on a clear day and a great climb right out of BCEP. Geology:The Three Sisters formed within the past 100,000 years as part of the High Cascades, a string of similar volanoes that extends from California to British Columbia. North Sister, the oldest of the "sisters," has been eroded to a summit plug of dangerous crags. South Sister, the youngest, still retains its uneroded conical shape. Its summit crater contains the state's highest lake, Teardrop Pool.
