Broken Top
This peak is #34 on the Height List for Oregon . This peak is #46 in Prominence List for Oregon .Broken Top is the decaying remnant of an extinct volcano located in the Three Sisters wilderness. The northwest ridge is the standard route. Class 4 on bad rock. Broken Top is the oldest and most eroded of the five major volcanoes in the Three Sisters region. Several hundred-thousand years ago its summit probably topped 10000 ft (3000 m) as do the present summits of the Three Sisters, but glacial erosion has now removed all of the original surface and carved deep into the interior, revealing the innermost structure of the volcano. The highest remaining points form a horseshoe open to the south, surrounding what was once the crater of the original volcano. Glaciers continue to grind away at Broken Top today: the Crook Glacier occupies the central portion of the crater bowl, while the Bend Glacier flows in a series of jagged tongues down the steep northern flanks of the summit ridge. Although the uppermost rotten lava pinnacles are never quite skiable, there are a number of worthwhile ski routes both inside the steep confines of the crater and along the somewhat gentler ridges and flanks on the outside. In addition, Broken Top has relatively easy access throughout the winter and early spring from the Mount Bachelor Ski Area, while all of the roads accessing the central portion of the Three Sisters Wilderness are snowcovered for many miles.
