Flooding pummels Yellowstone region

HELENA, Mont. — Floodwaters higher than any in more than a century tore through Yellowstone National Park and surrounding areas, sweeping away houses, washing out bridges and roads, stranding tourists and residents, and prompting frantic helicopter and raft rescues.

The flooding across parts of southern Montana and northern Wyoming from days of rain and a rapidly melting snowpack indefinitely closed one of the nation’s most iconic parks just as a summer tourist season that draws millions of visitors was ramping up.

North of the park, hundreds of people remained isolated Tuesday after the Yellowstone River crested higher than ever recorded in a chocolate brown torrent that washed away anything in its path. While no one has been reported killed or injured, waters were only starting to recede Tuesday and the full extent of the destruction wasn’t yet known.

“It is just the scariest river ever,” Kate Gomez of Santa Fe, New Mexico, said Tuesday. “Anything that falls into that river is gone. The swells are huge and it’s just mud and silt.”

Gomez and her husband were among hundreds of tourists stuck in Gardiner, Montana, a town of about 800 residents at the north entrance to the park. The town was cut off for more than a day until Tuesday afternoon, when crews managed to get part of a washed away two-lane road reopened. Officials warned that driving conditions were still dangerous.

While the flooding can’t directly be attributed to climate change, it came as the Midwest and East Coast sizzle from a heat wave and other parts of the West burn from an early wildfire season amid a persistent drought that has increased the frequency and intensity of fires that are having broader impacts. Smoke from a fire in the mountains of Flagstaff, Arizona, could be seen in Colorado.

Rick Thoman, a climate specialist at the University of Alaska Fairbanks, said a warming environment makes extreme weather events more likely “than they would have been without the warming that human activity has caused.”

“Will Yellowstone have a repeat of this in five or even 50 years? Maybe not, but somewhere will have something equivalent or even more extreme,” he said.
