Did you know that beginning in 1914 and continuing until 1951, Yellowstone visitors could actually swim in a warm, geyser-fed pool near Old Faithful? This remarkable attraction, often called the Geyser Water Swimming Pool or Old Faithful Bathhouse, was supplied with hot water piped in from Solitary Geyser. Initially constructed by Henry J. Brothers and later modernized by Charles A. Hamilton, the bathhouse included a spacious log pool, dressing rooms, and even a lifeguard tower reaching 25 feet high. Eventually, changing health standards and growing emphasis on conserving Yellowstone’s natural features led to its closure in 1951.
Remarkably, the diversion of water to supply the pool triggered Solitary Geyser to erupt regularly—a behavior that continued even after the pool was removed and natural water levels were restored.
This video not only delves into that fascinating chapter of Yellowstone’s history but also brings you up to date on recent geothermal activity: in May 2024, a geyser in Biscuit Basin experienced a hydrothermal explosion, and seismic monitoring recorded numerous earthquakes across the park—reminding us that Yellowstone’s underground systems remain as dynamic as ever.
