Extreme Flooding Devastates Yellowstone National Park, Forcing Closures and Evacuations

Unprecedented Flooding

Yellowstone National Park has been hit by unprecedented flooding, forcing the closure of all park entrances due to “extremely hazardous conditions,” according to a statement from park officials. The extreme weather has also caused significant damage to homes and infrastructure in communities near the park.

Causes of the Flooding

The flooding was caused by heavy rains that fell over the weekend and into Monday, brought by a storm system known as an “atmospheric river.” This surge of concentrated moisture swept in from the Pacific Ocean and across the northern Rockies, also bringing record rainfall to Washington and Oregon last week.

Prior to the storm, unseasonably warm temperatures in the Rockies caused increased snowmelt, which contributed to the flooding. The Yellowstone River and its tributary, the Gardner River, received an “unprecedented” amount of rain, causing the Yellowstone River’s waters to rise from 6 feet to 15 feet in just 24 hours.

Damage and Evacuations

The flooding has caused significant damage to roads and bridges, including a washed-out bridge over Rescue Creek. Rock slides have also occurred, further hindering access to the park.

Entire homes have been swept away by the floodwaters, and many residents are stranded in their homes or have been evacuated. Emergency responders are conducting airlifts to rescue people from their homes and from the water.

Impacted Communities

The flooding has had a devastating impact on communities near the park, including Gardiner, Cooke City, and Silver Gate, Montana. These towns are isolated due to washed-out roads and bridges.

Response and Recovery

Park staff evacuated visitors from the northern section of the park, where there were multiple road and bridge failures, mudslides, and other issues. They also moved visitors out of the park’s southern loop due to concerns about water and wastewater.

Montana’s Governor, Greg Gianforte, issued a statewide disaster declaration to help impacted communities recover.

150th Anniversary Commemorations Affected

The flooding will likely affect the park’s 150th anniversary commemorations this year. The park’s headquarters, museum, and archives are located at the northern entrance, which is currently closed. The Roosevelt Arch, where Native American groups planned to erect a teepee village, is also located at the northern entrance.

Ongoing Situation

The park’s entrances will remain closed through at least Wednesday, and possibly longer, depending on the severity of the damage and the time needed for repairs. Park officials are monitoring the situation and will provide updates as more information becomes available.
