Highline Traverse

Just drove up Mirror Lake hwy from Evanston and left a car at the snowline -- 9k. Now heading to Henry's Fork where we will start the traverse. Brother Sam is my partner for this excursion. We are hoping to do it in a single push, but conditions are warm and probably slower than we would like. We have 1 sleeping bag and some mylar to get us through a night if necessary.  I'm a bit frustrated because my pack is heavy -- about 16 lbs. We'll see how it goes!
