must-see destinations in the Marble Mountains

[corvus]

Hey folks, I'm looking for suggestions for a Marble Mountains trip in early mid July. Thinking in the range of 30 miles -- we acquired a person with a little less fitness and more knee issues, so we're thinking we'll average 7 miles/day for four days, plus two layover days for day hikes. We have one car, so definitely a loop.

So, tell me what you love, what I shouldn't miss, in the Marbles.
