Beware of avy danger on this one.
Form the parking lot at the summit of Berthoud pass, skin all the way up the Mainline Approach
. Start climbing the east face of Mt. Russell, the North Chutes open up just below the summit. There are a few options from here, drop into the largest of the chutes. There will be a large cliff band skiers right as you drop in about half way down, and then the run will open up.
