Madison Museum

The Madison Museum is one of a series of "trailside museums" in Yellowstone National Park designed by architect Herbert Maier in a style that has become known as National Park Service Rustic. It was listed on the National Register of Historic Places in 1982, and is one of three parts of a 1987-declared National Historic Landmark, the Norris, Madison, and Fishing Bridge Museums. Built in 1929, the Madison Museum is the smallest of the three. It is sited on a small rise that overlooks the meadows and canyon of the Madison River, and still fulfills its function as an informal interpretive center.
