Mudslides wreak havoc on major route
DENVER — As ominous storm clouds gathered in western Colorado over a large area blackened by a recent wildfire, torrential rain fell and the charred land stripped of vegetation gave way, sending a rush of mud and boulders tumbling down steep canyon walls and onto a major highway.
The July 29 mudslides stranded more than 100 people in their vehicles overnight and caused extensive damage that closed Interstate 70, capping several weeks of perilous conditions in a scenic canyon carved through the mountains by the Colorado River.
It marked the latest in a string of closures over the past two years for an area that also serves as a key transportation corridor between the Rocky Mountains and the West Coast. Each forced long detours for semitrailers that deliver fuel and food, and inflicted economic pain on businesses that cater to tourists in the popular summer destination of Glenwood Springs.
The closures illustrate the kind of damage scientists have long warned can follow wildfires made worse by climate change: dangerous mudslides caused by rain in burn-scarred terrain. Though no injuries were reported, such slides have caused deaths and destruction in recent years in California and other parts of the U.S. West.
Those who live and work in the Glenwood Canyon area have been adjusting to the inconveniences of closures for years, but mudslides have become more frequent and intense since the Grizzly Creek Fire scorched about 50 square miles last summer.
Transportation officials have closed a 46-mile stretch of the interstate and are telling motorists traveling between Denver and Glenwood Springs, on the west end of the canyon, to take another route that adds about 250 miles to the trip. Meanwhile, long-haul truckers have been advised to detour north onto Interstate 80 through Wyoming until the canyon is reopened, which could take weeks.
On average, thousands of commercial vehicles travel daily on the interstate through the canyon, according to state transportation officials.
Much of the fuel, food and other products that are distributed in the western part of the state come from Denver via I-70, and the detours are adding several hours to each trip, said Greg Fulton, president and CEO of the Colorado Motor Carriers Association.
In some cases, that means truckers can’t make the round trip without running afoul of federal limits on how long they can be behind the wheel.
“This is a ripple effect because we’re not getting the truck back until the next day. … It takes it out of sync in terms of those drivers, and effectively, you need more drivers and more trucks,” said Fulton, who warned that the delays could lead to gas and food shortages, late deliveries and higher prices.
“When we’re bearing additional mileage and we’re having additional time, and then even possibly bearing the cost of a motel room, that has to be passed on at some point,” he said.
The mudslides also have significantly impacted tourism in Glenwood Springs, which typically attracts thousands of visitors this time of year for its hiking, biking, fishing and other outdoor activities.
Lisa Langer, the city’s tourism director, said many attractions and some hotels went from full occupancy to being half-full, and some lost between 25% and 50% of their normal revenue during the weekend following the canyon’s closure.
The biggest problem is people from Front Range cities such as Denver canceling their trips because they don’t want to take the long detour, said Langer, who has shifted her focus toward attracting tourists from areas that still have easy access.
Meanwhile, whitewater rafting companies have had to reroute their itineraries, and some businesses have been shortstaffed because employees live on the other end of the closed interstate, an engineering marvel that winds through a narrow passage constrained by the Colorado River and cliffs towering hundreds of feet.
Max Vogelman, who co-owns Stoneyard Distillery, said the closure has had a “pretty huge” effect on the finances and logistics of his business, which makes alcoholic spirits from sugar beets.
The company opened a tasting room in Glenwood Springs in May, but the distillery is at the other end of the canyon, in Dotsero.
Vogelman said the company’s sole employee in Glenwood Springs has picked up extra shifts to keep the tasting room open, and another worker in Dotsero has been traveling nearly an hour out of her way on a series of winding, dirt roads every few days to deliver supplies.
