Norris Geyser Basin contains the hottest, oldest, and most dynamic thermal features in Yellowstone National Park. Here, you’ll find Steamboat Geyser, the world’s largest, shooting water more than 300 feet (though eruptions are quite rare.)
The Fountain Paint Pots are named for their red, yellow and brown colors, derived from the mixture of acid, clay and minerals that make up the bubbling mud.
The Grand Prismatic Spring is Yellowstone’s largest hot spring and its vivid spectrum of colors is a must to see.
Old Faithful, the park’s most famous attraction, is notable for its predictability to within 10 minutes, erupting every 65 to 92 minutes to heights of 106 to 184 feet.
