The 94-foot (29 m) by 20-foot (6.1 m) museum consists of two rectangular sections divided by the breezeway, which is roofed by a prominent jerkinhead gable., framed in massive logs. The pavilions to either side are of shingle-coveredframe construction on a massive stone base. A stone and concrete terrace surrounds the building.
A nearby comfort station or toilet is included in the National Register nomination. It was probably built in the 1930s. With the construction of a modern facility the one story log structure is now used as a bookstore operated by the Yellowstone Association.
The museum exhibits focus on geothermal geology, features of Norris Geyser and plant and animal life in thermal areas.
