Atheys Run Map

To approach, park at the S curves in Big Cottonwood canyon and follow the creek up to the Mill B trailhead. Follow the summer trail up into the drainage until you reach the lakes. Cross over the lakes and head to the SW branch of the upper canyon. Work your way through the rolling hills and benches until you see the gully itself, then climb up it.


From the Little Cottonwood Canyon Ridgeline this steep chute runs down off the ridge for almost one thousand feet before it drops through some playful rolling terrain in the lovely upper basin of Mill B. There's still plenty of skiing to be done as you wind your way through the aspen trees and finally end up skiing back down the approach route. A long tour, but worth the effort with the beautiful views and huge amount of skiable vertical. You might even run into the ever ornery Bob Athey.



Serious gradient of 30-38 degrees where a real risk of slipping exists.
