Park at the Bostock Day Use Area and follow the Bostock summer trail for just over a kilometer. Leave the summer trail (right turn) and make your way up the shoulder. The tour up through the tall trees on McGill Shoulder is nice but can seem like an eternity. Once a tree-line, there are a few options. Ski the McGill glades if visibility or snow stability is an issue. When the trees start to thicken, you can cut back onto the shoulder and hook up with your skin track for another lap or continue heading down to the summer trail. If you’re more confident in the stability, head up a bit higher on the shoulder and cut over to the gun barrels just skier’s right of the glades and the main slide paths even further skier’s right. These are usually skied right to the summer trail, roughly 50m above the creek. Once you’ve hit the summer trail, you can follow it out or head over to the other side of the creek and skin up Christiana Shoulder for some mellow yet fun tree skiing.

Another option off McGill Shoulder are the E/SE facing Camp West lines. These are visible from the highway.
