As we’re waiting for spring… Alabama is relatively green in the winter too!
These images are false color images, shown in colors chosen to enhance certain features. Healthy vegetation shows as bright red (evergreens in these winter shots), while sand, stone and concrete are shown in a white-blueish color. Considering this you can see Tuscaloosa as a whiteish blob to the left and Birmingham a bit northeast of it. Using this palette water bodies typically occur black (see top of photo), but the Black Warrior River and Lake Tuscaloosa appear blue, probably due to a high sediment content.
The scans were made by Landsat Satellites in the winter of 1995-96. Courtesy of the Geological Survey of Alabama
