Google alerts, gave me today a a link to
PASA , they are CEMEX Maderas partners.
You will see that on their introductory page , the first thing that pops up is the El Carmen Mountains, in full bloom if i may add.
I started navegating their page and found this:
Museo Maderas Del Carmen. I strongly recommend you to navigate this page, it shows where the camps used to be, before they were converted to scientific sights, and donīt forget to click their "Activities" link , check their pictures gallery as well.
