Rampage is short, but well worth the time and effort. It's a pretty unique hanging ramp in the upper Mill B drainage. You'll want to boot, and/or skin up this line to know what conditions are like. Park at the S curve 4.3 miles up Big Cottonwood Canyon, and hike up the Mill B trail to Lake Blanche. From the lakes head up the E branch of the upper canyon. Keep going into the uppermost cirque and you'll see Rampage. This is your only real entry option as it's very hard to get to any other way.
