No one really thinks of the Chilliwack Valley as a destination for alpine snow and ice routes, but the Priest/Coupe on Rexford, and the north couloirs on the Pleiades, seem like good climbs. I haven't climbed them myself though so I can't proclaim them to be sleeper classics or chestbeat about being the only cascadeclimber to have done them. They might suck. Getting to the start of the Pleiades routes would certainly be a major thrash unless Red Mountain Mine Trail has been freshly brushed out (last pruned in 1999 that I know of)
