It turns out that a large number of crannogs, manmade islands in Scottish lochs made by basically piling rocks in the water until you have stacked enough of them atop the pile to stick up out of the lake, date back further than expected. Given that doing amazing things with big rocks was something of a national pastime in Neolithic Britain, this is less surprising to me than it probably should be.
