WAPITI, Wyo. -- Several thousand cars, trucks and recreational vehicles were backed up in long lines at entrances to Yellowstone National Park as it partially reopened Wednesday morning following record floods that reshaped the park's rivers and canyons, wiped out numerous roads and left some areas famous for their wildlife viewing inaccessible, possibly for months to come.
Park managers raised the gates at three of Yellowstone's five entrances for the first time since June 13, when 10,000 visitors were ordered out after rivers across northern Wyoming and southern Montana surged over their banks following a torrent of rainfall that accelerated the spring snowmelt. The cost and scope of the damage is still being assessed, Yellowstone Superintendent Cam Sholly said Wednesday.
Some of the premier attractions at America's first national park will again be viewable, including Old Faithful - the legendary geyser that shoots towering bursts of steaming water almost like clockwork more than a dozen times a day.
But the bears, wolves and bison that roam the wild Lamar Valley and the thermal features around Mammoth Hot Springs will remain out of reach. The wildlife-rich northern half of the park will be shuttered until at least early July, and key routes into the park remain severed near the Montana tourist towns of Gardiner, Red Lodge and Cooke City.
It's unknown how many visitors will show up in the flooding's immediate aftermath, but the lines indicate many tourists stuck to their plans despite uncertainty last week about when it would reopen. Sholly estimated 2,000-3,000 vehicles entered in the first few hours.
License plates at the east entrance near Wapiti, Wyoming, indicated they were from Indiana, Arkansas, Ohio, Colorado, British Columbia in Canada and other places. The first visitors going through didn't have to contend with other traffic, but they had to watch for marmots on the road.
Park managers had been bracing for throngs as the park celebrated its 150th anniversary a year after it tallied a record 4.9 million visits.
Muris Demirovic, 43, of Miami and his 70-year-old mother arrived at the east entrance at about 5:30 a.m. Wednesday and were second in a line of dozens of cars. He and his mother, who is from Bosnia, were on a cross country trip visiting national parks and Yellowstone was at the top of their list.
However, when they arrived, it was closed due to flooding. Demirovic and his mother toured Cody, Wyoming, went to a rodeo, walked some trails and visited a museum. They had planned to leave the Yellowstone area on Monday, but stayed when they learned the park would re-open this week.
"This is a once-in-a-lifetime trip for me and my mom, so I had to make sure she sees this," he said.
To keep visitor numbers down while repairs continue, park managers will use a system that only allows cars with even-numbered last digits on their license plates to enter on even days, while vehicles with odd-numbered last numbers can come on odd days.
Groups of visitors traveling together in different cars are exempt from the license plate system as well as people with reservations at campgrounds and hotels in the park.
If traffic along the park's 400 miles (644 kilometers) of roads becomes unmanageable, Sholly said officials will impose a reservation system to enter the park.
Along the road to Yellowstone's south entrance in Wyoming, a long and slow-moving line of cars snaked along a road with a sign that had been flashing "Yellowstone closed" for days but on Wednesday alerted drivers that the park was open but with restricted access.
"We were hoping to be in at a decent hour but it doesn't look like that's going to happen," said Gracie Brennan of Kentucky, gesturing to the line.
Brennan and two of her friends were going to Yellowstone as part of a tour of various national parks. They were supposed to be on the road Wednesday to the Badlands but changed their plans.
"Old Faithful was the main thing I wanted to see, so if we can get there, which ever way we got to go, it doesn't really matter," Brennan said.
The reopening comes as officials in Yellowstone are still tallying the extent of the damage. Based on other national park disasters, it could take years and carry a steep price tag to rebuild. It's an environmentally sensitive landscape with a huge underground plumbing system that feeds into the park's geysers, hot springs and other thermal features. Construction season only runs from the spring thaw until the first snowfall, a narrow window that means some roads could receive only temporary fixes this year.
That's turned some Montana communities into dead ends instead of being gateways to Yellowstone, a blow to their tourism-dependent economies. They're also still struggling to clean up damage to several hundred homes and businesses that were swamped by flooding on the Yellowstone, Stillwater and Clarks Fork rivers.
In Red Lodge, one of those gateway towns cut off from the park, most businesses are open even as flood cleanup continues. The Montana Department of Transportation is beginning repairs to the road between Red Lodge and the scenic Beartooth Highway and the National Park Service is working to restore access to some areas in the northern part of the park.
"We have to remain optimistic, but we also have to remain realistic that there's a lot of things going on and a lot of moving pieces to make it happen," said Tim Weamer, who does marketing for the Red Lodge Chamber of Commerce.
"We're optimistic that we'll survive," he said. "We're not going to have the summer we were hoping for."
For others the rebound may come faster. Yellowstone tour guide Derek Draimin said Tuesday he was fully booked up Wednesday with four groups that will be headed into the park. He expected large crowds of people hoping to be among the first inside after the rare and record flooding.
Draimin lost about 25 tours because of the flood but said he and others could get a bump as tourists who can't get in through the park's northern entrances get funneled through West Yellowstone, where his company, Yellowstone Adventure Tours, is based.
Montana Gov. Greg Gianforte, who received criticism last week for not disclosing he was out of the country until two days after the flooding hit Yellowstone and parts of southern Montana, was not at the park for Wednesday's reopening.
Spokesperson Brooke Stroyke said Gianforte was scheduled to meet with Cabinet members and be briefed on flood response and recovery in his state. Some flooding is also occurring in the Flathead Valley in western Montana, where a man died in a rafting accident on the swollen Flathead River on Tuesday.
Wyoming Gov. Mark Gordon also wasn't in the park, said his spokesperson Michael Pearlman.
Tiffany Jahn from Kenosha, Wisconsin, who was with her husband and daughter in the line at the south entrance in Wyoming, said she was excited to see anything that was still open and especially hoping to catch a glimpse of the park's wildlife.
"We were actually coming last week and we were getting messages ... saying 'Don't come, don't come,'" she said. "But we were already out here so we kind of just altered our plans and made it work. "
