Catherine and Gregg just completed two amazing poster sessions displaying there work on the Big Darby River, Ohio and Panamanian weathering. (I took the below pic of Berry sampling Catherine's site).
I'm already counting on eating blocks of cheese (or another high fat Peruvian food) in an alternating sequence with chocolate to deal with high altitude headaches and hunger. I suppose aspirin and some time away from the computer will also help. I also just realized that the bus from Lima to Huaraz is an 8 hour segment. I'll keep the end in mind. Jeff sent some amazing pics his brother took on their last visit!
