sulfuric lake (Score 1)

So this is only marginally on topic, but the story reminded me of a video I saw when I was a kid, I think featuring the Kraffts, that talked about a sulfuric lake caused by volcanic activity. I seem to recall the hosts of the video talking about someone's skin being eaten away by the acid in the lake, but I can't find anything on it in a quick google search. Has anyone else heard about this lake or this gruesome skin story? Now I've got the image in my head and I want to read more about it. I'm drawn to it like a train wreck. Well, a train carrying vats of sulfuric acid, at least.
