Aah, the old "what the heck is the altitude for a mountain in Argentina" problem. Some of the Argentine border mountains are 500+ meters higher on the Argentine maps than the Chile maps!! For some reason it seems hard to determine the correct altitude of many Argentine mountains!
Nice page, I have two minor comments:
1) I added a page on Supercanaleta, although I agree with your recommendation of sending people to the local experts.
2) Direct-direct is a misleading name for a very indirect route.
