Is Yellowstone Closed? NO! Biscuit Basin Explosion: Understanding Yellowstone’s Latest Geothermal Event

Yellowstone National Park, a crown jewel of the American wilderness, has once again demonstrated its dynamic nature with a recent explosion at Biscuit Basin. This event has captured the attention of park enthusiasts, scientists, and potential visitors alike, highlighting the ever-changing landscape of this geothermal wonderland.

But to start, no Yellowstone is not closed. A small section of the park (Biscuit Basin) remains closed after the recent hydrothermal explosion – but there are other geysers to see! We are excited to welcome you.

What Happened at Biscuit Basin?

A hydrothermal explosion took place at Yellowstone National Park‘s Biscuit Basin in northwest Wyoming Tuesday morning (July 23, 2024), sending boiling water and steam into the air and causing some damage to a boardwalk, officials said.

The small, localized eruption occurred at 10:19 a.m. local time near the Sapphire Pool, which is about two miles northwest of the Old Faithful Geyser, the National Park Service said.

The basin, including the parking lot and boardwalks, is temporarily closed until park officials determine the area is safe.

“Hydrothermal explosions, being episodes of water suddenly flashing to steam, are notoriously hard to predict,” the U.S. Geological Survey said on social media. The agency likened the eruptions to a pressure cooker, adding that “they may not give warning signs at all.”

The Geological Marvel of Yellowstone:

Yellowstone National Park sits atop one of the world’s largest active volcanic systems, often referred to as a supervolcano. This underground powerhouse fuels the park’s famous geothermal features, including geysers, hot springs, mud pots, and fumaroles. Biscuit Basin, located in the Upper Geyser Basin area, is renowned for its colorful hot springs and geysers, making it a popular stop for park visitors.

The recent explosion at Biscuit Basin serves as a vivid reminder of the park’s ongoing geological processes. These events, while rare, are a natural part of Yellowstone’s lifecycle and provide valuable insights into the park’s subterranean activity.

Understanding Geothermal Activity in Yellowstone:

Geothermal features like those found in Biscuit Basin are the result of complex interactions between water, heat, and underground rock formations. As groundwater seeps into the earth, it’s heated by magma chambers deep below the surface. This superheated water then rises back up through cracks and fissures, creating the spectacular displays we see at the surface.

The Biscuit Basin area is particularly known for its clear, blue hot springs and small geysers. The basin’s name comes from the biscuit-like deposits of siliceous sinter that form around some of its features. These formations are created when dissolved silica in the hot water precipitates as it cools, gradually building up over time.

Safety Considerations for Visitors:

In light of the recent event at Biscuit Basin, it’s crucial to reiterate the importance of visitor safety in Yellowstone. The park’s geothermal areas, while beautiful, can be dangerous if proper precautions aren’t taken. Here are some essential safety guidelines:

Always stay on designated boardwalks and trails. The ground in thermal areas can be thin and fragile, with scalding water just below the surface.
Follow all park ranger instructions and posted signs. These are in place for your safety and the preservation of the park’s natural features.
Keep a safe distance from geothermal features. Not only is approaching them dangerous, but it can also damage these delicate ecosystems.
Never touch or attempt to test the temperature of hot springs or geysers. The water in these features can be near boiling and cause severe burns.
Keep a close eye on children and pets, ensuring they understand and follow safety rules.
Do not throw objects into thermal features. This can damage the features and is illegal.

Impact on Yellowstone Visits:

While the Biscuit Basin explosion may have altered the immediate area, it’s important to note that Yellowstone National Park remains a vast and diverse destination with numerous attractions. The park spans nearly 3,500 square miles, offering a wealth of natural wonders beyond its geothermal features. Some key attractions include:

Old Faithful Geyser: Perhaps the park’s most famous feature, Old Faithful continues to erupt regularly, drawing crowds with its impressive display.
Grand Prismatic Spring: The largest hot spring in the United States, known for its striking rainbow colors.
Mammoth Hot Springs: A unique area where hot springs have created terraces of travertine formations.
Wildlife viewing in Lamar and Hayden Valleys: Known affectionately as the “Serengeti of America,” these areas are known for wildlife observation. Keep an eye out for bear, bison, elk, eagles, coyotes and even wolves.
The Grand Canyon of the Yellowstone: A spectacular gorge carved by the Yellowstone River, featuring dramatic waterfalls and colorful rock walls.

Planning Your Visit:

Despite the recent event at Biscuit Basin, Yellowstone continues to welcome visitors year-round. Here are some tips for planning your trip:

Check the official Yellowstone National Park website regularly for the latest updates on park conditions and any area closures.
Consider staying in West Yellowstone, Montana, for easy access to the park. This gateway community offers a variety of accommodations and is just minutes from the park’s west entrance.
Book accommodations well in advance, especially if you’re planning to visit during the peak summer season (June through August).
Explore alternative geothermal areas like Norris Geyser Basin or Mud Volcano. These areas offer equally fascinating glimpses into Yellowstone’s geothermal activity.
Plan for varying weather conditions. Yellowstone’s weather can be unpredictable, so pack layers and be prepared for sudden changes.
Try visiting during the shoulder seasons (spring and fall) for a less crowded experience.

The Scientific Value of Geothermal Events:

Events like the Biscuit Basin explosion provide valuable data for scientists studying Yellowstone’s geology. These occurrences help researchers better understand the park’s underground systems and can potentially aid in predicting future geothermal activity. Visitors to Yellowstone have the unique opportunity to witness firsthand the type of geological processes that have shaped our planet over millions of years.

The recent explosion at Biscuit Basin serves as a powerful reminder of Yellowstone’s status as a living, breathing geological wonder. While such events may temporarily alter certain areas of the park, they also reinforce the raw beauty and power that make Yellowstone a truly one-of-a-kind destination.

As we learn about these natural phenomena, it’s crucial to approach our visits with respect for the park’s power and adherence to safety guidelines. By doing so, we can safely enjoy the unparalleled experiences that Yellowstone offers, from its geothermal wonders to its diverse wildlife and stunning landscapes.

Whether you’re a first-time visitor or a seasoned Yellowstone enthusiast, the park continues to offer new experiences and insights with each visit. The dynamic nature of places like Biscuit Basin ensures that no two trips to Yellowstone are ever quite the same.
