Thanks for the help everyone.
Right now the plan is to show up at the Ranger Station early Friday 7/17 and try to snag Cottonwood Lakes permits. If we don't get them I'll see what else is available. If we can't find any overnight permits that interests us, we'll track down Gary and hang out for the day,

then try Langley as a day hike.
I am probably headed up to White Mountain Peak this weekend, and may take a shot at Mt. Barcroft while I'm up there. Have any of you done this? Is there a use trail?
