I have seen the word "Calero" used for the high camp on the normal route. The correct name is Coléra, sometimes spelled Choléra (scary name )
There may be new rules coming up for next year. A proposal from the government states that it wants to minimize the number of agencies in the park. Obviously it will only be five admitted into the park next season and all the other ones will be sub-contractors. I have no idea how this will affect the situation for the climbing community, but there are fears that the costs for services will rise a lot.
Permit fees may also be higher for next season and the off season climbing may be heavily restricted.
Nothing is written in stone yet, but this was the last I heard when leaving Argentina.
