Great trip report! I did Boundary last year during the 4th of July weekend. There wasn't nearly as much snow up there last year. Your "leafy greens" are called Mules Ear. Evidently they make spectacular flowers, too. I think they're pretty enough just w/ their greens!
Glad you had a great trip. I just returned from Whitney: http://shelleypotts.com/AboutMe/HighPoints/CA.php
