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.
