First trip to the volcano zone

On Friday we went to the lakes to the northwest, closer to the Puyahue eruption and near the devastated town of Villa la Angostura.  (full set of pictures at: LINK)   The crew consisted of me, Monica, Esteban Balseiro, and postdoc Marcela Bastidas.  The picture below is from Lake Espejo Grande, and shows the dock and “beach”.  Obviously, a lot of pumice has accumulated here, on the downwind side.  The turquoise color of the water is also a sign of the volcano – normally the lake is dark blue and super-transparent.  Along with many other lakes, it now has the turquoise cloudiness like a lake receiving glacial flour.  But the cloudiness is from the suspended ash.  Despite a steady rain, we took pumice samples here and in an arm of Lake Nahuel Huapi, as well as water samples in a shallow lake called Lago Pire.

Pumice accumulated at the downwind end of Lago Espejo Grande, ~20 km from the Puyahue Volcano
