Enjoy your trip out there. This was my first time in GNP and after what I saw I can say that it won't be my last. The wildflowers were just starting to come out up on Logan Pass so you may find more when you go. We saw lots of Glacier Lilies up there. Down lower we found lots of Scarlet Paintbrush along the trails.
Most of the trails were open. The rangers were still cautioning casual hikers against going to Grinnell Glacier because of snow/ice on the trail recommending that unless you had snow/ice climbing equipment it might be better to wait. Maybe it has cleared by now.
Thanks for you comments on my photograph. As I get around to processing more I'll post them.
