No hoards of people here. Salmon La Sac was apparently a great choice for some snow play yesterday.
The road is plowed to the snow park(s), but is definitely icy with compact snow in places. I never noticed any dicy areas, but I was driving an AWD car, so I can't say how it would have been otherwise. It was lumpy in places, but I doubt there was anything that would have bothered a low clearance car. We arrived relatively early (probably around 8:30), but there were a fair number of snow mobilers that were already parked and away.
After crossing the bridge into the park we encountered no one until quite late in the day. We didn't even hear any snow mobiles, except for once on the lower portion of the Cooper River trail - they must have been on the road that goes up the other side.
There's probably around 3-6 feet of snow on the ground depending on how it's piled up and drifted. You will need snowshoes or skis to go pretty much anywhere off of the road. The ski trails had not been groomed. We wandered a bit before figuring out we had to ignore all of the Private Property signs and actually go up the road to the right a bit - all of the landmarks, like the gate and signs are either buried or no longer existing… so go to the right just after crossing the bridge, then as the buried road appears to Y take the left fork (not toward the Cle Elum river and cabins) - the road will become relatively defined and you'll find the trailheads - the tops of the trailhead signboards are just visible. There are two trail heads quite close together. Go up the hill to the left of the further sign to reach the Cooper river trail.
There'd been no other people there at all since the last snowfall, so we were breaking trail pretty much anywhere we went - it was definitely hard work. The snow was very powdery and while the snowshoes definitely kept us close to the top (they are a style that work best on Cascade concrete.. more than powder snow), we were probably going in a foot or two. The snow in the campground area was probably actually harder break trail on than the snow on the trail - more trees to keep it a little more compact and shallower? but still there were drifts and loose spots. I went in a soft spot once to about my hip (in a little V too, so snow on either side was about shoulder height..), and had to dig out a bit, but never felt like I was in danger of being buried. The actual trail wasn't really at all apparent. Using a GPS we wandered around somewhere within about 40 feet of it most of the time, but if you are up there, don't expect to follow our track and be accurate…. Breaking trail and climbing was pretty exhausting, so we didn't really go up very far, I think about 1/3rd of the way to the lake, before deciding that we should turn around. Going back in our own track (and down) was much, much quicker than we expected, even though I wouldn't really say that once over by two people completely packed it down, so we decided to ramble around the campground area for a while before heading back to the car. We stopped to have some nice hot soup in the partially buried shelter before walking the river bank for a while and then circling around back through the campground. It was probably around 3pm as we were heading back out to the car that we finally encountered a few groups of people coming in to wander the campground. All had snowshoes. We saw some ski tracks when we got back down from the trail, but they were using our previously broken trail and only went about 4 feet further than where we'd made our original wrong turn before they turned around… I guess it may have been too hard going for skis. In all we travelled around 7 miles, with probably 2/3rds breaking our own trail and a little doubling back. While I'm surprised to not be sore today, we sure were tired yesterday.

One interesting thing - while we could definitely see that there were blowdowns in places - the large downed tree shaped snow lumps - there was so much snow that we never actually had to really climb over them… the snow would just push out the way/pack down to make the track nearly level...
Oh - and frozen gummy bears are awesome :)
