Floods wipe out roads, bridges, strand visitors
Record flooding and rockslides unleashed by an unprecedented burst of heavy rains prompted the rare closure on Monday of all five entrances to Yellowstone National Park at the start of the summer tourist season, the park superintendent said.
The entire park, spanning parts of Wyoming, Montana and Idaho, in the western United States, will remain closed to visitors, including those with lodging and camping reservations, at least through Wednesday, as officials inspect damage to roads, bridges and other facilities.
The closures come as Yellowstone was gearing up to celebrate its 150th anniversary year, and as local communities heavily dependent on tourism were counting on a rebound following COVID-19 travel restrictions over the past two summers.
All five park entrances were closed to inbound traffic for the first summer since a series of devastating wildfires in 1988. The National Park Service said it was working to evacuate visitors and staff remaining at various locations, especially in the hardest-hit northern flank of Yellowstone.
“It is likely that the northern loop will be closed for a substantial amount of time,” the park superintendent, Cam Sholly, said in a statement.
There were no immediate reports of injuries, though dozens of stranded campers had to be rescued by raft in south-central Montana. Authorities also said they would be assessing a potential “loss of homes and structures” in Montana’s Stillwater County.
Elsewhere, some of the worst damage happened in the northern part of the Yellowstone and the park’s gateway communities in southern Montana. National Park Service photos of northern Yellowstone showed a landslide, a bridge washed out over a creek, and roads badly undercut by churning floodwaters of the Gardner and Lamar rivers.
In south-central Montana, flooding on the Stillwater River stranded 68 people at a campground. Stillwater County Emergency Services agencies and crews with the Stillwater Mine rescued people Monday from the Woodbine Campground by raft. Some roads in the area were closed due to flooding, and residents have been evacuated.
The “gateway” community of Gardiner, Montana, just beyond the park’s northern boundary and home to many of Yellowstone’s workers, was cut off by a mudslide to the north and washed-out road surfaces to the south, according to the National Park Service.
Aerial footage released by the Park Service showed large swaths of the winding North Entrance Road between Gardiner and park headquarters in Mammoth Hot Springs, Wyoming, carved away by surging floodwaters along the Gardner River – washouts that will likely take months to fully repair.
Power outages were scattered throughout the park, and preliminary assessments showed numerous roadways across Yellowstone either washed away or covered in rocks and mud, with a number of bridges also damaged, the agency said.
Various roads in the park’s southern region were on the verge of being flooded, with more rain in the forecast.
The Yellowstone River at Corwin Springs crested at 13.88 feet (4.2 meters) Monday, higher than the previous record of 11.5 feet (3.5 meters) set in 1918, according the the National Weather Service.
The flooding and slides were triggered by days of torrential showers in the park and steady rains across much of the wider Intermountain West following one of the region’s wettest springs in many years. The park service characterized the rainfall and floods sweeping the park as unprecedented, with the Yellowstone River topping its banks beyond record levels.
A sudden spike in summer temperatures during the past three days also has hastened melting and runoff of snow accumulated in the park’s higher elevations from late-winter storms.
The heavy rains and rapid runoff of snow melt converged to create treacherous conditions in the park just two weeks after the traditional Memorial Day holiday weekend kickoff of the U.S. summer tourist season, which accounts of the bulk of Yellowstone’s annual 4 million visitors.
Yellowstone, established as the world’s first national park in 1872 and treasured as one of America’s top outdoor travel destinations, occupies some 2.2 million acres (890,308 hectares) famed for its geysers, abundant wildlife and spectacular scenery. (AP/Reuters)
