Description
Geologists believe that the Three Sisters region was originally covered by one great mountain which they call Mount Multnomah. The top and center of this mountain was blown off by a terrific explosion leaving fragments in a great circle. From the north these fragments are the North Sister, the Husband, the Wife, Devil's Hill and Broken Top. The Middle and South Sisters were thrown up by later volcanic action. This would make the North Sister the oldest of the peaks.
