Snow / terrain conditions for Mt St Helens or Adam in Southern WA Cascades Posted May 11, 2013 I'm looking to climb Mt St Helens (possibly Adams) in late May or early June. I no longer live in the NW so I'm not sure what the snow pack has been like. Is the snow pack pretty much the same as last year or is there less/more? Also, recent weather conditions (surprisingly warm for Apr and May) makes me wonder if I'll be able to take the "monitor ridge" route. Any input you can provide would be great.
