The Three Sisters volcanoes in Oregon are beautiful but one of the three is dangerous. The photo above shows Middle Sister, a dormant volcano​, and North Sister, an extinct volcano. Their other sibling, South Sister, is the troublemaker. This volcano last erupted about 2,000 years ago and research in 2000 indicated uplifting activity so it could blow again. See all three Sisters in the photo below. South Sister is on the left  – some distance from her siblings.
