|Colima volcano, Mexico, eruption March 2005|
There is a pyroclastic flow running down the left side of the volcano in addition to the obvious ash cloud. My friend Karen was in the middle of presenting the details of some older volcanic deposits when Emilio started shouting, "!El volcan! El volcan!" and we all turned around to see it erupting! Pretty darn spectacular.

And to bring this post back to gardening, volcanic soils are some of the most fertile in the world. There's a reason the flanks of Vesuvius are covered in farms; it's just too bad she's gonna blow again one of these days. But in the meantime, she might as well help provide food and wine, right?
This concludes our geologic interlude. Here's hoping Grimsvotn doesn't mess things up too badly for air travel... and hoping a certain geologist I know doesn't get stranded in Greenland!
