Can you give me a little more on the creeks?  The big creek that used to be unofficially bridged by a nasty old slanty log...is the nasty old slanty log history?  Do you think that one is unlikely to survive vigorous melt days?  Vesper is a fantastsic set of transitions from nasty miniforest, to green ferny hillside, to mega N basin, mini-gulley, talus field, and fun upper slopes...I love it.
