Aquatic Vegetation, Yellowstone River, Wyoming

(Click image to enlarge)

The vegetation shown in this photograph is growing on the bottom of the Yellowstone River under several feet of water. Use of a polarizing filter and meticulous positioning to eliminate reflections and glare from the water's surface make it look almost like there is no water present. River bottom Vegetation like this makes an ideal habitat for fish like the native cutthroat trout and the aquatic creatures and insects they eat.
