Fellow SP member "Gimpilator" and I did this as a one-day trek, via Longs Pass and Cascadian Couloir. 8000' total elevation gain and 13.25 hours (including one hour at the summit). Perfect weather conditions, and the awesome view from the summit made the entire climb worth it. One of my all-time favorite climbs.
The "permanent" snowfield below the false summit was completely melted out, and that loose gulley was the crux. We exited the gully to the left ASAP, and made one fourth class move (no exposure) down a narrow opening in the SSW ridge heading up to the false summit. Then it was easy scrambling through boulders to the summit.
