GARDINER, Mont. – Yellowstone National Park officials assessed widespread damage Tuesday as the park remained closed amid dangerous floods, mudslides and rockslides that have eroded roads, ripped apart bridges and forced evacuations this week.

The water started to slowly recede Tuesday and one key highway reopened, but the record-level floods left all five entrances to the park closed through at least Wednesday, officials said. And, officials said during an update on Tuesday, the water levels could still change at any time.

“The water is still raging,” said Park Superintendent Cam Sholly, who added that more wet weather was forecast this weekend, which could cause additional flooding.

The park, which is celebrating its 150th anniversary this year, has seen multiple road and bridge failures, power outages and mudslides, causing the evacuations of more than 10,000 visitors from the park.  

“I’ve never seen this, not in my lifetime,” said Austin King, a firefighter and EMT in Gardiner, a town just outside Yellowstone’s busy northern entrance.

There were no reports of injuries or deaths as of Tuesday afternoon, but floodwaters swept away a number of homes, bridges and other structures. The northern part of the park suffered the worst damage. 

The full scope of the damage was not known Tuesday, leaving it unclear when roads might reopen or when residents in neighboring communities might be able to return.

The northern loop of Yellowstone National Park was cleared of visitors and park officials were working to evacuate visitors in the southern area of the park Tuesday. Park staff were searching for five back-country groups to ensure they were safely evacuated. 

Meanwhile, Montana Gov. Greg Gianforte declared a statewide disaster and said the Montana National Guard rescued 12 people stranded by high waters in Roscoe and Cooke City.

The Yellowstone River reached highs of almost 14 feet on Monday, far higher than the record 11.5 feet set more than a century ago, according the the National Weather Service.

Although the water was still “extremely” high, a route out of Gardiner, a town of about 900 people, reopened Tuesday afternoon, according to county Commissioner Bill Berg and Sholly.
