Hi there, currently I am training to hike Desolation another time in July.  It is proving to be more difficult since I am now 71.  The ” space ” between training enough to make it to the top and the risk of training  injuries — is a pretty small window of success.  Not sure how it is going to go—having some left knee issues and L ilioband soreness…….  If only I was young again  : )  bruce
