On July 23, 2024, an unexpected hydrothermal eruption occurred at Biscuit Basin, north of the renowned Old Faithful Geyser in Yellowstone National Park. At approximately 10 AM local time, visitors were startled as steam, dark-colored rocks, and dirt shot up into the sky, creating a dramatic spectacle. Online footage captured dozens of spectators initially observing the event from a nearby boardwalk, only to start fleeing as the eruption intensified.

Impact on Biscuit Basin and Visitor Safety
The sudden eruption caused significant damage to the infrastructure of Biscuit Basin, particularly the wooden boardwalks designed to protect and maintain a safe distance between visitors and the park’s geothermal features. Following the event, park officials promptly closed the affected area to assess and repair the damage. This closure was a precautionary measure to ensure visitor safety, as falling debris during the eruption had compromised the structural integrity of the pathways.
Eyewitness Accounts
Vlada March, a visitor from California and a real estate agent, described the event as sudden and overwhelming. “We saw more steam coming up, and within seconds, it became this huge thing,” she recounted. March, who her family accompanied, described the steam cloud as becoming so dense and expansive that it obscured the sun. Videos and photos posted by witnesses showed the chaos as people scrambled to safety, with some shouting warnings to others as the area around them was engulfed by debris.
Scientific Explanation and Investigation
Scientists from the Yellowstone Volcano Observatory were quick to investigate the eruption. According to Mike Poland, a leading scientist at the observatory, the eruption likely resulted from a clogged passageway within Yellowstone’s complex underground hydrothermal system. This blockage could have led to a build-up of heat and pressure, eventually causing water to flash into steam and triggering the explosive event. Such phenomena, Poland explained, are similar to what occurs in a pressure cooker.
Historical Context and Safety Precautions
Yellowstone National Park is situated atop a massive dormant volcano, and its landscape is dotted with numerous geothermal features, including geysers and hot springs. Although less known than eruptions like Old Faithful, hydrothermal explosions represent a significant natural hazard. The park’s history includes various incidents related to these features, with at least 22 recorded fatalities due to thermal injuries since 1890.
Park authorities warn visitors to adhere to safety guidelines, including on designated boardwalks and trails. The ground in thermal areas can be deceivingly fragile, covering boiling or acidic waters beneath. This recent eruption serves as a potent reminder of the inherent dangers posed by the park’s dynamic and volatile geothermal activity.
As Yellowstone continues to attract visitors with its unique natural beauty, this event underscores the importance of respecting the park’s regulations and remaining vigilant while enjoying its wonders.
