I spent the last weekend in Crested Butte and couldn't make it up on Green Mountain to see what's happening. On the other hand, it's interesting to compare the two areas. Through the Gunnison valley the trees are just greening up, so I was surprised to see a few wildflowers blooming in Crested Butte. Chiming Bells, Mountain Candy Tuft and a few buttercups were flowering in the woods. Along a creek were some marsh marigolds, whose original genus name, Psychrophilla, means "cold-lover".
I'll update on GM as soon as I can get up there.
