Unfortunately Johnston ridge is the only real option this time of year for views. The road to Marblemount Sno-park is closed right now too. Yeah, the road past Coldwater Lake is closed this time of year but, you can still hike up the road, or the Hummocks trail, to the observatory. Right now it will be snowshoeing, and easier to follow the road. However, it’s roughly 7 miles to the observatory, or 6.5 to the Loowit viewpoint each way. The Hummucks trail is 9.5 round trip, but you’d want to check NWAC for avalanche prediction, and have route finding skills. The lower part of the trail would be fine for tromping around, and there are some sneak peaks before you start to climb higher. If that interests you, there are plenty of places that rent out snowshoes between PDX and Mt St Helen. The most recent trip report I found, here, was from the 7th. Says there was about 2 feet of snow on the ground at Coldwater. It’s supposed to be warm this week, but the snow level isn’t predicted to go higher than 3700’ and the observatory is at roughly 4300’. So, there will definitely be fresh snow up top.
