Translation of cleavage in Spanish

I would like to give you a proofreader's project. Proof reading sample sentences that were entered into the dictionary by our users. It is a very tough project and needs a lot of discipline and patience.
Sometimes I visit Vocabulix to meet new people. It is true that one could do the same on Facebook, but the FB page is rather for friends, and you are less likely to contact strangers for this purpose.
I'd be very happy if you could correct my Spanish. In return, I'll help you too, of course. 3 years ago I traveled to Chile to visit the country, only for a month, unfortunately. Loved the Cordillera!
