Who wants to scuba-dive in a weird grey moonscape? This Argentine dude apparently does. The moonscape is Nahuel Huapí, which is normally a nice clear alpine lake in southern Argentina, and it looks like that now because it got a liberal dusting of ash from the recently-erupted Puyehue volcano in neighboring Chile. The same has disrupted air travel in Chile, Argentina, Uruguay and Brazil with its massive ash cloud, which can clog the engines of jet aircraft and makes visibility extremely poor for pilots. Airlines from as far away as Australia and New Zealand have had to cancel flights because of it, although service is now starting to resume.
I can only imagine what it must be like trying to see through water darkened with a heavy layer of ash. Let’s hope this lake is clearer underneath that surface!
