Yep, it sure is. It was with mixed feelings that I took this picture though. It's a beautiful volcano, and the lama completes the picture, but at the same time I was a bit sad because only the day before we were so close - but we had to turn down from high camp because of very strong winds.
Well, they are domesticated, but roam free. The ones in Sajama NP are both curious and apprehensive, so, when we were looking at them from a safe distance, some looked back at us, as if standing guard, while the rest kept on grazing.
Approaching them real slowly worked only up to a point, then they moved away. Not abruptly, but deliberately, as if to maintain a safe distance.
On another occasion, on the altiplano near the Cordillera Real, we encountered a herd with a handler and they were much more docile.
