Ski tour to Green Mt today.  Our party of 3 only ones on the mountain. Suiattle River Rd not bad.  Potholes once pavement ends, but fairly easy to navigate around or through slowly.  Gravel road up to TH pretty smooth.   Trail clear until about 5000 ft with patchy snow, we transitioned to skins about 5100 ft.  Traveled up middle-looker's left of basin below the lookout, booted up the last 4th. Saw tracks following the summer trail going right and presumably up the looker's right ridge line.  Large cornices and steep drop off along SW ridge but easy to avoid.  Spent a few minutes on the lookout deck (what a spot! Glacier Peak! Mt. Baker!) then started ski back down.  Upon cutting across the top of the bowl S of the lookout I set off a series of D2 wet loose avalanches that ran the entirety of the bowl.  I was able to ski out (the continued skiing out is what kept setting off more wet loose) until the slope angle lessened, then our party carefully picked our way down.  It was nerve-wracking and unexpected.  Snow sun-softened but only a handful of small rollers on the way up that did not propagate at all  In retrospect, boots sinking well above ankle on the final walk-up should have been our clue.  Falsely expecting stable spring conditions.  Looks like you could maybe link snow to ski from 4800 to intersect with trail below, but we'd had enough adventure so passed on trying.  Absolutely gorgeous area, and grateful we came out with some good lessons learned.

Decided to try for Green Mountain today as we wanted to do one more fire lookout trip in the snow and this one seemed more doable in shoulder season as long as we could access the road.

We couldn't find any recent TR and wasn't sure how far we could drive on Suiattle River Rd. To our surprise, the road was snow free all the way to the trailhead and there were no major obstacles on the road except for small blowdowns, potholes, and some small rockfall debris. I think all cars can make it but high clearance vehicles are recommended.

Trail was snow free until we were above 4,400 ft, pretty much after the forest section. Switchbacks were covered in patchy, slushy snow, some were covered in old avalanche debris, and mostly were in springmelt conditions. 

We put on spikes not long after that for more comfort, as we did some sidehilling. We switched to snowshoes at around 5,200ft as we started postholing and everything was snow covered. Probably should've kept our spikes as there's a stretch of narrow sidehilling in the forest just before the lake.

After the lake, we generally tried to follow the summer route but there were also old snowshoe tracks that we were able to follow. For the last 200 ft before the summit, we deviated a bit more NE from the old snowshoe tracks, so it was a bit more direct and steep but we also avoided getting too close to the cornice.

Summit view was wonderful with Glacier Peak looking really close. The lookout was closed but we were able to access the viewing area. 

On the way down, we were able to glissade down almost to the basin, so it was pretty fun.

Stats: I accidentally paused my GPS, so I believe it's around 8 mi RT, 3K elevation gain, a little over 7 hours total time with a relaxed pace. My additional old GPS watch is wonky so I don't trust its stats haha.

Gears: Spikes, ice axe, helmet, snowshoes (only needed snowshoes for a short period, so you may not need them but they were pretty helpful).

Beautiful day, but ultimately turned around (see below):

Road: some debris but everything was passable with high clearance vehicle. There was snow about 1 mile from trailhead that AWD and high clearance was helpful for.

Trail: got an early start, and avy conditions were moderate per NWAC. As I exited the forest, there were two recent decent-sized avalanche debris fields on south facing aspects in obvious avalanche terrain. I saw some rollerballs higher up and with all those signs I turned around as there was still a decent amount of avalanche terrain to traverse to the summit.

Road is snow-free to the TH.  Trail is snow-free to about 4600 feet, give or take - pretty much to where the forest thins out at the second major switchback where the trail starts heading east across the mountain.  The accumulation at this elevation isn't much - maybe a foot or so - so avalanche danger along this long traverse isn't a concern....yet.  By about 5600 feet the snow is above the knees.  I foolishly convinced my group to leave our snowshoes in the car ("nah, we won't need them; it's too early in the season!"), so this was the point we turned back.  There was one other party on the mountain, and they were able to skin up beyond where we bailed.
