Well although you can't see the switchbacks in <a href="http://community.webshots.com/photo/167774896/172730460EDZIXb">this picture</a>, I'll explain where they go. It starts into the rubbles field to the far right of the pass, then traverses into the cliffs to the right of the pass. The really difficult part comes near the base of the small snow field in my picture, where the trail crosses the chute. Many have said that this covered in snow is really scary, and a large cornice can hold on top of the pass as well. This pic was taken July 2nd last year, prob a month ahead of this years melt.
