What was destroyed in Yellowstone?

The flood destroyed several sections of the North Entrance Road between Mammoth Hot Springs, Wyoming, and Gardiner, Montana, and three sections of the Northeast Entrance Road between Lamar Valley and Cooke City/Silver Gate, Montana.



Yellowstone National Park has faced two major historical events that resulted in significant destruction: the 1988 wildfires and the 2022 historic floods. In 1988, roughly 36% of the park (about 793,000 acres) was burned by massive forest fires that destroyed iconic landscapes and some historic structures, although the ecosystem has since remarkably recovered. More recently, in June 2022, a "500-year flood event" caused by unprecedented rainfall and snowmelt devastated the park's northern region. The floods destroyed miles of the North Entrance road, severed the Mammoth wastewater line (causing sewage to flow into the Gardner River), and wiped out bridges and trails. Entire communities like Gardiner, Montana, were isolated as roads collapsed into the river. In 2026, while many roads have been rebuilt, the scars of the flood are still visible in the altered river channels and the ongoing reconstruction of permanent infrastructure. These events serve as a stark reminder of the power of nature and the vulnerability of even our most protected wilderness areas to extreme environmental shifts.

Old Faithful is a cone geyser in Yellowstone National Park in Wyoming, United States.

It is a highly predictable geothermal feature and has erupted every 44 minutes to two hours since 2000.
