In a dense swampland in Georgia, just north of the Florida border, you find the headwaters of the Suwannee River. The Suwannee is known as a “blackwater river” because of its dark-brown waters laden with organic material. This river system has been called one of the most pristine in the United States, but some environmental pressures are putting that distinction in jeopardy. When the river finally meets the Gulf of Mexico along Florida’s Big Bend its dark waters act like a tracer, revealing whereby the river water mixes with the sea. That mixing was on display on February 20, 2015, when the Operational Land Imager on Landsat 8 captured this view. Image: NASA.
