Another eruption?

It certainly looks like another eruption. But looks can be deceiving. The mountain that we could normally see in this direction is Chimborazo and it is snow-covered, but you can't see it from this location. It is actually behind the hill which you just see.

The way the clouds are formed in this photo it certainly looks like a BIG mountain and an erupting one as well. Or, maybe it's just my imagination!
