Norris Geyser Basin has some of the park's most unpredictable and fascinating geothermal features. Its 2½ miles of trails takes you past thermal geysers, rainbow colored hot springs and impressive fumaroles that make up Yellowstone's hottest features.

Located 1/4 mile east of Norris Junction just off the Grand Loop Road, you'll find the Norris Geyser Basin Museum, which is one of the park's original trailside museums built in 1929-30. Some of the museums in the park we once buildings used for other things, but this one was always a museum.

It is a National Historic Landmark with its distinctive log and stone architecture and was a prototype for park buildings throughout the country known as "parkitecture" (Fishing Bridge Museum and Madison Museum date from the same time period and are of the same style). =]:)
