Apart from the first few km of road, the approach on the Singing Pass trail was much more enjoyable than I expected, even with an overnight pack. Once in the park, the trail climbs steadily through some lovely forest. Climbing out of Singing Pass is a bit of a slog, coming at the end of a long hike. The route back over the Musical Bumps has tremendous views, but the sun was merciless. We left at 8 am to try and beat the heat, with limited success, and enjoyed every patch of shade we could get our hands on. Lucia gelato at the Roundhouse was very welcome!
The washout at Harmony Creek is quite a sight, and would be quite tricky in times of high water. I can only see that getting more difficult with time as the trail is already up against a cliff and crumbling fast. All other creek crossings were fine. There's another big washout along the road with a welcome fixed rope to help climb up.
The lake was busy with at least a dozen tents, probably more (I wasn't counting), many of which had nowhere else to go but directly on the meadows. A group was camped up on the southern end of Cowboy Ridge - hopefully they practiced leave no trace camping. (Personally I would have gone a bit further so I was out of sight from the trail.) It's a good spot to watch sunset/sunrise though.
One of the stay cables on the outhouse has broken. TP may or may not be present - if so, do not expect it to last. Bringing your own is highly recommended. The hut has some hooks and nails for hanging food bags.
Flowers are mostly done, though a few local hot-spots remain. Partridgefoot is probably at its peak, as is elephant ears. Wet areas contain lots of leatherleaf saxifrage and alpine willowherb. A few patches of pink monkeyflower, and even some yellow monkeyflower by the outlet creek from Russet Lake. Up on Cowboy Ridge there are a couple of rich paintbrush meadows.
Wildlife: lots of birdsong at the lake, and in the forest on the way up. A few marmots including a family near where the trail crests Cowboy Ridge. Bugs were annoying to the point where I actually used a deet wipe on my legs and arms. Nasty but it worked. Grasshoppers were everywhere....
All in all it was simply a delight to spend a peaceful night up at the lake again. It's a beautiful location.
