Ruskin says: "Mountains are the beginning and the end of all scenery." "Oregon without Mt. Hood, Mt. Jefferson, and the Three Sisters; Washington without Mts. St. Helens, Adams, and Rainier would be robbed of half their scenic charms," says Finchk.
The Three Sisters, a series of red and black lava cones, constitutes the central part of the Cascade region of Oregon. In elevation they rise between 10,000 and 10,500 feet.
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.
