Yes, people have been in there this season. She's good to go except for Pine Tree falls. Never been on the White or Little, but their reputations preceed them as difficult runs. The gorge is a huge step up in difficulty and especially commitment over the runs you've done in CO. You might find someone on here, but it's a better bet to get in with the local scene out there and make a connection. It'd be a rough day without a guide your first time.
