What was found at the bottom of Lake Michigan?

There are some odd geological finds at the bottom, including a 2007 archeological find that was described as Stonehenge-like, although it was actually more in a V-shape. One of the stones is said to have a mastodon image on it (although it's not fully clear if it was man-made or just a natural formation).
