Llaima official IGM elevation is 3125m.
No idea where that 3050m number on the map comes from. Stick to official numbers (unless it is an Argentine Map) if in doubt.
Nice page otherwise. Will browse through more and see if I can add something.
Thanks for your comment, I update the page, and double-checked all altitudes. I'll be please for more information if you have any, I can add up.
Feel free to vote ;o)
