This route is popularly known as the East Face - it is an improbably steep-looking face that turns out to be quite reasonable. The climb involves a hike up to Cascade Pass. Then a traverse of scree and snow slopes along the east side of Mix-up Peak to the glacier basin below the east face. In late season a moat forms between the snow and rock in the gully that leads to the notch. Once at the notch you'll find class 3 & 4 climbing with a final 5.0 pitch to the summit.
