slaphat:

today i found out that when monarch butterflies migrate south for the winter, all the ones that go across the middle of lake superior suddenly stop going south and go west for five miles and then continue south. which really freaked scientists out cos like What is in the Middle of Lake Superior what do Butterflies know that We Dont Is This The End Times etc. anyway turns out about a hundred million years ago there was a mountain there and the butterflies still think they gotta fly around it. classic butterflies
