I’m still out science traveling in Argentina with access by iPhone only. Yesterday I toured around the lake in Bariloche. One of the more interesting aspects was the remnants of the big 2011 volcanic eruption from Chile (the border is only a few kilometers from here).
See that sand alongside the stream? It’s not sand. It’s pumice from the volcano.
The ash was so thick it raised water levels for months. The water covered the roots of the stream side trees, hence the dead trees in the picture below.
On the lake itself the pumice, volcanic rock that is lighter than water, floats.
The beach of the lake is more pumice, at least 10-20 cm of it. That’s my host hopping across the ash/sand. And yes, there’s a story behind the broken leg. I’ll cover that when I get back to the states.
That’s all for now. Keep in mind these photos are all from my iPhone; the best photos are on the other two cameras. So much more to come.
Meanwhile, sales of Tesla: The Wizard of Electricity are still strong as the publisher readies the release of the second printing. Watch also for the Tesla and Renewable Energy ebook due out in late spring.
