Morning Glory Pool, Yellowstone National Park, Wyoming - a hot spring situated in the Upper Geyser Basin, named by Mrs E. N. McGowan, wife of assistant park superintendent, Charles McGowan in 1883. She called it "Convolutus," the Latin name for the morning glory flower, which the spring resembles. The distinct color of the pool is due to bacteria which inhabit the water. On a few rare occasions it has erupted as a geyser, usually following an earthquake or other nearby seismic activity.
