Park at the Great Divide Parking Area. Head across the road and along the creek into Chickadee Valley. The route generally follows along the creek for about 4km at which point the route veers slightly left into the trees. The trees will open up to an avalanche clearing off the bench. While gaining this bench and beyond, be aware of the steep east face of Whymper W1. Once on this bench, the remainder of the route will be clear. Head up the moraines to the next bench, then up the col. This is the steepest bit of the climb. From the top of the col, it’s a simple 160m bootpack to the summit. Descend the same way.
Along this route, there is also the X-Couloir. This is a steep and committing line. For more info on this objective check out Andrew Wexler’s post.
