They did encounter ice on the trail and still made it up to Blue Lake, although they said coming down was scarier on the ice they had to get around.
The last time I was on this hike it was mid-summer and there were more waterfalls than you could count! They are all frozen now.
This is one icy section of the trail that Jay took a picture of.
This bubbling waterfall is completely frozen over now. Jay said one more snow and it would take snowshoes to get up to Blue Lake.
