The steep, narrow, and dark couloir seen from the top. Hopefully, if you climb Chisholm via Overlook but want to use the couloir to avoid reclimbing Overlook on the way back, this photo will help you locate the correct route.

The couloir has two short Class 4 sections near the top and then becomes a trip on snow or very loose talus.
