An Oddity

If you look at a map of the Maumee watershed, you'll notice something very odd. Usually, a river's tributaries flow in the same general direction as the river itself. With the Maumee, that pattern is reversed. The tributaries flow toward the Maumee's source. This is because, due to tricks of glaciation, millenia ago, the Maumee has changed direction. It originally flowed into the Wabash.
