There is still quite a lot of snow on the trails. On the way to Black Lake, I put the spikes on where the outlet of Blue Lake falls across the Black Lake trail. From there to Black Lake is was almost entirely snow. Above Black Lake it's snowy to the top of the chute you climb to access Blue, Green, and Frozen Lakes. Once to the top of that chute, snow is less present as the area is bathed in sun all day.
The weather was unbeatable - not a cloud in the brilliant blue skies and calm.
I probably wouldn't have continued over the snow on the approach to Black Lake without spikes, but I was about the only one so equipped. Lots of people did it in sneakers.
I had intended to scout the river crossing for the hike to Shelf/Solitude but managed to miss the spot both ways. No matter; I won't likely hike there until August or September.
