Ski-resort in Brazil?

[Pitz]

I own an old ski-book in that is written a short note about an ski-resort in Brazil.
The only information is that it was closed in the 1970s. It was an resort with natural snow, none of these dry-slpoes you have in Brazil.

Does anybody have some information about this site (name, location ec.)?

If in portugese/spanish I will try to understand too, but better in english or german.
