Yesterday (9/1) we hiked in to the base of the friction slab of the SW face. After climbing the face we topped out at the tree and the pack was sitting right where you said Thomas! Thank you so much for moving it there as it made for an easy rescue. Had you taken it to Ingalls Pass it almost certainly would have been long gone.
I sent you a PM about picking up the rope. I am glad to meet you locally during your trip. Also, I have friends going to Portland for 9/14-9/16 who said they would be glad to pick to the rope up for me. I put my email address in the PM so if you get a chance drop me a note and let me know what works for you.
The climb up the SW face was super easy but thin for pro. It was a FULL 60m rope length to the tree. A single rope rap might have gotten you to a small ledge but I didn't see anything one could used to sling a rappel anchor, but I didn't look that hard. The double rope rappel was just enough to reach the bottom. The down climbing would have been super easy but a slip would have been messy. I am glad the rope was there for you.
