I'll drill it down for you goaty.
Been into the Pickets many times, but never entered from Canada via Lil' Chilli (bordering Manning Park, that's the Canada part) and never topped out on Phantom Pk - always wanted to do both....cross W-pass, up and over the N ridge (very fun), cross C-glacier (slog), down into Luna Crk basin (majorly sucks) and up Phantom's E face. Thing that sticks, and is always the case w/ the P's, is you are stuck securing a shuttle or haulin' it back the way you came.
An addendum would be to by-pass W-com and up Easy Rg.
Is it crystal?
