Patagonia - unclimbed peaks

I'm looking to plan a trip into Patagonia sometime in 2012, and I'd love to try for a first ascent. Does anyone out there know of a good source for figuring out what's been done and what hasn't?

American Alpine Journal... the whole thing is searchable by keyword online. Take a look at the Cordillera Darwin - absolutely shit weather, but apparently some of it hasn't even been really mapped well yet, and it took 3 or 4 expeditions for them to figure out which one was actually Monte Darwin. There was an interesting write-up about the range in the journal a few years back, with a summary of the expeditions so far (something like 20 total).

AAJ for sure, plus the web at large. There is so much stuff still to be done in the region (East Face of San Lorenzo, anyone?) most of it guarded by atrocious multi-day approaches. If you're looking at stuff in the Chalten area I'm sure Mr. Garibotti could help you out on info (if he hasn't done it first.

You gotta go there, climb some of the established routes, check out what looks good or climbable, then reference the huge stacks of topos and ascent information available in the park office (Chalten). For the Paine it is a bit harder to track down route info, but it is there. So, you pretty much have to go there, and figure it out in person. Searching through AAJ back issues isn´t gonna help too much.

Suerte!
