Very nice pictures. We used to sometimes drive up there even earlier in the year and the ice cone around the base of the falls would be complete so it would just look like the falls were dumping into the top of a big cup of ice.
Green mountain lookout in the park also has some nice views. And if you're up for a bit of a hike, the trophy mountain/meadows trail leads up to a nice alpine meadow that can be absolutely stuffed with wildflowers if you can get up there at the right time of year.
