The photo shows the West and East notches of the Spider-Formidable Col as seen from the Flat Creek Cirque (i.e. looking north onto the south face). I haven't met anyone who has done the West notch and in fact at least in an early edition of Beckies guide, he recommends the East notch. As you can see the West notch cliffs out. When we came through the East notch on 25 July 2006, the snow was good for steep steps and a good run out existed at the bottom. I recommend taking the East notch.
