Mima Mounds continue to mystify scientists
There’s a large swath of native prairie southwest of Olympia that’s very strange looking. So strange, in fact, that some have even said it was created by aliens.
What makes it strange are “things” called The Mima Mounds.
We can tell you some things they are not, but we can’t tell you what they are. In fact, people have been trying to figure them out for centuries.
“It’s probably one of the most poorly understood phenomena in earth science,” says Paul Butler, professor emeritus of Earth Science at the Evergreen State College.
