I thought this mountain and cloud formation was too perfect to ignore. Clouds always do strange things when they pass over mountains, but this one seemed particularly violent and unexpected. This is not actually a volcano. it's just a regular old mountain in the Andes that had a nice little volcanic shape. I skirted around it for a while (skirting is quite a trek at this radius), until the angle seemed about right... although I had to skirt fast before the clouds changed. I have always wanted to take a photo of a volcano that is erupting. I climbed up part of a volcano that was erupting in Costa Rica, and you could see the red rocks, but I got absolutely zero good shots. Oh well... some day!
