Upon leaving Mammoth Hot Springs, on the way back to West Yellowstone,
you come upon Norris Geyser Basin. Its geysers spout at frequent
intervals and its steam vents noisily erupt great volumes of vapor.
Constant, Minute Man and Whirligig are some of the geysers. Emerald,
Opal, Iris and Congress are a few of the pools.

Enchanting Gibbon Falls will add another lingering memory of your trip
through Norris Geyser Basin.
