White Chuck/Gerdine/Cool Glacier Route

My attempt at line route description for the Gerdine/Cool Glacier route. This picture is from near Glacier Gap, after climbing through what was The White Chuck Glacier. There is an excellent photo of route when there was a White Chuck Glacier in the Becky book page 94 and 95. At the top of my line, the route is a short trip up the Cool Gacier to the obvious pumice ridge (in Sept), leading to the summit.
