Went for a nice overnight trip from Carbon River entrance of Mt. Rainier to Carbon River Camp. I haven't been on the Carbon River Rd since it washed out (the most recent time) - it's much worse and wiped out a lot more trail than the previous washout. A LOT of big trees down in the riverbed and from being undermined along the trail/road/new channel. If you didn't know, the Wonderland between the Northern Loop Trail and Carbon River Camp is out too, so you need to cross the river twice to get there. The trail is mostly pretty good, with bridges etc, but one re-route was pretty muddy.
We hiked up the Spray Park trail, but only as far as Cataract Camp before running out of time. Not much snow to speak of before Cataract Camp (but some), and despite the Park Service website, most tent sites there are under snow; only 2 might be usable, and those pretty damp. I assume the trail is snowed in not far above. This trail was a little overgrown, and will get more so as things leaf out.
We saw quite a few day hikers and bicyclists on the way in, but no one else at our camp, and only one party was scheduled to be at Ipsut Creek Camp. Saw only 1 person the whole day Monday, he headed in as we headed out.
Saw quite a few flowers including: Scouler's Corydalis (lots), Ribes, glacier lilies, yellow violets, Caltha, buttercups.
Had a nice bear viewing below the trail not far in from Ipsut Creek Campground. Also saw a bunch of deer, a frog and some chipmunks.
The carnage along the river is really quite impressive. A lot of very big trees strewn around - some from 2006, some more recent.
The ranger station was staffed on Sunday.
