Nearly a year ago, a large explosion in the Biscuit Basin originated from the Black Diamond Pool. This explosion was due to hydrothermal activity and caused alarming amounts of boiling water, steam, and debris to be sent into the air.
The explosion also destroyed the boardwalk, which was an important infrastructure for guests to move around and watch the majesty of the pools. Thankfully, as dangerous as the explosion was, there were no injuries. However, the resulting aftermath and uncertainty of future seismic activity meant that the area was shut off from visitors.
Closed For Nearly A Year
After the initial explosion, efforts to clean up the mess began. But nearly a year later, Biscuit Basin is still closed to park guests. Reconstruction efforts were impeded due to safety concerns, meaning the future of Biscuit Basin as a park attraction is uncertain.
The National Park Service and Yellowstone Volcano Observatory cite concerns and continue monitoring for future activity and associated risks. Any hopes that it would be reopened have been dashed by the unstable nature of the area, with small geothermal events occurring since the July 2024 event.
Hydrothermal Explosions
Hydrothermal explosions are natural events caused by subterranean water getting trapped and quickly turning into steam from incredible temperatures. This creates substantial pressure, which builds up before eventually letting it out somewhere, usually to the surface.
This process can be incredibly violent, and the explosion can send debris flying and superheated steam everywhere, making it a matter of health and safety for guests. Contrary to what many believe, this isn’t due to volcanic activity but the area’s geothermal plumbing system.
The Results Of The Explosion
The area around the Black Diamond Pool was left in ruins, and the landscape was permanently altered, showcasing how unpredictable and potent Mother Nature can be. Rocks displaced by the explosion were effortlessly ejected despite weighing hundreds of pounds.
Since then, the unstable nature of the site has meant that any hopes of renovation and reopening have been halted. The site is always being monitored and is still deemed a hazard for guests and faculty responsible for renovations.
Ongoing Activity
Despite the large explosion almost a year ago, scientists have monitored the area and registered smaller events from Black Diamond Pool. The biggest of these small-scale events were in November last year and January 2025.
This showcases that the area is still very active, and nobody knows when things will calm down completely. Even if these smaller events do not pose as much risk as the first one, they prove that the area could still have a dramatic event like the one in July 2024.
How The Site Is Monitored
Park officials are monitoring the site using various technological tools, including sensors that detect seismic activity, GPS stations that track changes in the area, and webcams that monitor the site directly.
These tools combined create a sophisticated way of tracking geothermal changes and events in Biscuit Basin. Only once these events substantially calm down will the park continue efforts to reopen the once-popular attraction. Public safety is the park’s biggest concern, and only once there is nearly a zero chance of an imminent event will things change.
Effects On Visitor Traffic
Biscuit Basin is a renowned spot in Yellowstone that attracts numerous visitors annually. However, with the park closing for nearly a year, guests have been locked off to an important location, which could be driving traffic down.
Local businesses, such as hotels, tour operators, and restaurants in nearby towns like Gardiner and West Yellowstone, depend on heavy foot traffic to stay afloat.
Visitors are less likely to go to Yellowstone if their favorite attraction is inaccessible, even if it’s for a good reason. This could lead to slight economic implications for the park and surrounding areas.
Beauty Comes With Danger
Part of the attraction of Yellowstone is its location, which is on top of an enormous volcanic hotspot. However, the explosion that happened at Biscuit Basin and subsequent instability are not indications of volcanic eruptions and activity but rather of the park’s underground geothermal system, which can cause immense pressure.
The volcanic activity is also constantly monitored but does not pose any risks to the park at present. The explosion is a reminder that Yellowstone is a part of the untamed landscape in an inherently unstable yet beautiful place.
Lessons To Be Learned
The explosion that happened last year has prompted park officials to look at safety measures and visitor awareness of park dangers. Better and more transparent signage has since gone up, updating visitors about Biscuit Basin’s status.
Visitors also have something to learn from this, which is to stay safe by keeping to marked trails and obeying the park orders, including zones marked off limits. Guests need to admire the majesty of Yellowstone while respecting the forces of Mother Nature.
The Future Of Biscuit Basin
The effect that Biscuit Basin’s closure has had on the park is not inconsequential, with fewer visitors coming through the park. The question then stands: when will the area be reopened for everyone? For now, it seems that officials have tried being as transparent as possible, with statements that the area remains closed for the 2025 summer season at the very least.
While many might think this is unfair, it’s all in the interest of guest safety. While the park remains closed, scientific research is being conducted to better understand hydrothermal systems and how they change after large explosions. Patience is required for now, and once all is clear, visitors will be able to go to their favorite park location once again.
