Waiting on Parinacota

My guide is waiting patiently on what might well be the summit. I wasn't sure about that, there were several local high points on the rim that looked like they might be higher. Besides, now that the sun was out, the temperature was quite nice and I felt fine, so why not have a look? In total, I spent an hour or so hiking the rim and taking pictures before I got back.
At the time, I didn't have an altimeter, so I couldn't tell which of the many local summits was the real one ...
