Drifting Buoys Track Water Currents in the Great Lakes Straits of Mackinac

When you’re watching a river or the waves on a lake, do you ever wonder where that water goes? If you threw a rubber ducky into the water, where would it end up? Scientists are studying the movement of water in the Straits of Mackinac, which connect Lake Michigan and Lake Huron, to figure out how the water moves around. This water movement can affect ship traffic, how pollution spreads, and where aquatic animals go.

And the North American Anasazi channeled rainwater from mesa tops into stone-lined reservoirs. These history lessons were not lost on nature photographer Mike Halminski.
