Volcano Crater

Santorini is an island that would be more or less circular were it not for the volcano that blew out much of the island.  The crater was then filled by the sea, and so now the island is sort of crescent shaped, with the horns of the crescent trying to encircle the sea.  There are two new islands in the sea; one, the "old" one, formed in the mid-nineteenth century when the now-undersea volcano erupted again, and the second from around 1950.  These photos are of the second, newer island.  It's basically a heap of rocks with very sharp edges, since dirt hasn't had time to form yet.  We took a boat to fairly close (maybe 60-70 meters) to the island, then swam a few minutes through some cool water to get to an area of warm water heated by the volcano.  The warm water wasn't at the temperature of hot springs, but it was probably in the low to mid 90s, maybe 33-34 Celsius.  Near the island itself if you stick your foot down, you find this rust-covered sludge-like stuff.  We asked the boat captain what it was, and he said "slimy mud," but I suppose that's it's scientific name.  Anyway, it was weird.  We smelled like sulfur the next day and a half.
