It sounds like the consensus is to do a day trip first and then plan a backpack trip.
If you're interested in Skyline Lake near Stevens Pass, we could hike to the lake (it's only an hour or so from the Pass and not much of a destination in itself), up and over Skyline ridge, down Moonlight Bowl, hop onto the PCT, and hike back to the Pass for a nice loop trip. Edited for clarification – this is a snowshoe hike. Both the Skyline and Lake Valhalla suggestions are subject to monitoring the avalanche danger.
Or if you'd prefer Lake Valhalla and a different route than the standard Smithbrook Road route, we could do the long version from the Pass on the PCT, or drive 1.5 miles past the Pass to Yodelin and snowshoe to the lake via Nason Creek. I could show you Burns Butte that's right by the lake!
Hopefully we can come up with a good plan that includes as many as want to come and isn't delayed by holding out for a perfect plan.
So we need to pick a destination, then a date. I've already got a trip planned on the 7/8 of March. Who's going to spearhead all this? And should we do emails rather than clog the BPL site with planning?
