Mount Fitz Roy (3405m) lies in Los Glaciares National Park, Argentina and is considered one of the hardest peaks to climb on the planet due to severe and unpredictable weather. The ancient dwellers used to call this mountain “Chaltén”, a name that in the “ahónikenk” tongue means “smoking mountain”. Clouds that rest on its summit almost constantly, made old inhabitants of the area believe this was a volcano. Named Fitz Roy in 1877 in honor of the Captain of HMS Beagle.
