Nearly 50 years ago, the iron mining companies that were once the backbone of Crosby, Minnesota鈥檚 economy pulled the plug, leaving behind a scarred landscape of open pits and piles of unwanted red dirt. The area soon became an illegal dump that looked more like Mars than Earth, and the town became the kind of place where visitors locked their doors as they drove through.听Then in 1993, the mines and the surrounding land were designated a state recreation area to preserve their mining heritage, and the state cleaned it up as best it could, hauling truckfuls of garbage out. But no one visited much, and the area sat mostly forgotten and untouched. Over the next two decades,听the land recovered, Crosby did not.
. Members of an off-road cycling club from Minneapolis, 125 miles away, took one look at the red dirt landscape and fell in love. The 200-foot-tall听piles excavated during mining operations created a site ripe for trail building, and with the help of the , those cyclists successfully lobbied the state to create its first mountain-biking-focused state park. After local volunteers built a demo trail, the Department of Natural Resources hired a professional crew to put in 25 miles of flowing, technical singletrack, creating .听
鈥淲e call it Cuyuna Gold, the wonder dirt for mountain bicycling,鈥 says Aaron Hautala, volunteer president of the , the local IMBA club responsible for maintaining the trails.听

Almost as soon as the trails opened in 2011, Crosby was designated a bronze-level听IMBA ride center, a title which honors large-scale mountain biking facilities with trails for every skill level and rider type. Suddenly, tourists began arriving in town with bikes strapped to the back of their cars, Hautala says. The local bike shop鈥檚 map of visitors鈥 hometowns filled up with pins in nearly every state of the Union.
There鈥檚听data documenting the trails鈥 economic impact, too. According to a survey conducted by Hautala鈥檚 club and听IMBA, 25,000 cyclists a year ride the trails, adding an estimated $2 million to the local economy. That same survey predicts that number will increase to $21 million once the trails are expanded to the planned 75-mile total. 鈥淚t鈥檚 become this thing where people are like, 鈥榃ow, we鈥檙e coming back,鈥欌 Hautala says.

Fifteen new businesses have opened in Crosby since 2011, and the only thing that鈥檚 changed, Hautala says, is the singletrack that now winds through the woods outside town. There鈥檚 a , a yoga studio, two wood-fired pizza joints, and the , which caters to cyclists with six bike-in, lakefront cabins. More importantly, many of the business were started by young people who moved to the area or chose to stay because they see potential in the trails.听
Crosby is not alone. All across the county, single-resource towns are building trails where they once harvested timber or mined ore to attract a new source of revenue鈥攎ountain bikers. 听 听
鈥淲e鈥檙e an untapped resource,鈥 says Andy Williamson, who manages and as the organization鈥檚 director of program development. 鈥淭he idea of dirt bag mountain bikers going to places and sleeping in their cars isn鈥檛 really relevant anymore. We want to really experience the places we visit, and the communities that really embrace that are the ones that can take full advantage of us.鈥
According to a 听of more than 1,400 cyclists across the country, 62 percent of mountain bikers travel to ride, make an average of two trips a year, and spend about of $382 each trip. So at a relatively cheap $50,000 per mile of top-flight, professionally-built mountain bike trail, the return on investment can be 鈥渢ruly amazing,鈥 Williamson says.

Oakridge, Oregon, has become a poster child for the movement. Once a thriving lumber town in the heart of an old-growth forest, Oakridge took a nosedive in the 1990s after the local mill closed. In 2004, it received a grant to develop a trail plan, and the city began working to brand itself as mountain-biking destination. Today, it has over 380 miles of trails in the surrounding mountains.听y, mountain bike tourism generates as much as $5 million in direct spending each year.

鈥淭hat whole , mountain biking, and recreation,鈥 Williamson says. 鈥淓verybody from the mayor to the little ukulele shop in town are all at the table saying, 鈥楾his tourism is good for us.鈥欌澨
In Michigan, Copper Harbor, a former mining and port town on the Upper Peninsula with a population of just 108, . Weaverville, California, a former gold rush town then logging center reinvented itself again in the mid-1990s as an off-road biking destination specializing in long-distance trails. It now hosts several and in . In the South, it鈥檚 estimated the 22 miles of trails outside Anniston, Alabama, a former steel town in the tail end of the Appalachians, could generate $2 to $6 million dollars in economic impact annually. And in Northern British Columbia, another secured $1.5 million in grants to in an effort to attract visitors, and it鈥檚 working.听
鈥淚t really seems like a case of … if you build it, they will come,鈥 says Martin Littlejohn, executive director of British Columbia's Western Mountain Bike Tourism Association. 鈥淸But] it鈥檚 not just a tourist attraction, it is part of the local fabric.鈥澨

Nine other mostly resource-based towns in the region have also turned to mountain biking, Littlejohn says, to not only diversify and improve their economies, but also attract and retain young, skilled workers by improving quality of life. Their efforts were rewarded this year with a northern edition of the popular significantly raising the area鈥檚 profile as an outdoor recreation destination, and while there is no economic data yet for what effect mountain bike tourism has had there, that shows visiting mountain bikers in Squamish to the south spent $10 million and supported $15.6 million in economic activity in the province in 2016. 听 听
Even big cities like Chicago are buying in. Located in the city鈥檚 South Side on a former slag dump for heavy metals and other byproducts from nearby steel foundries, the 听combines ecological restoration with singletrack, gravity, and flow trails. 鈥淚t would be upwards of $200 million to remediate [the site],鈥 says Jay Readey, the interim director of , a coalition of companies and organizations supporting the park鈥檚 development. 鈥淭hat just wasn鈥檛 feasible, so to cap it and build a bike park on top of it is fantastic.鈥
More than 1,000 people showed up for opening day last November, which Readey hopes is a sign of things to come. 听

Back in Crosby, Hautala听isn't satisfied. He wants to not only expand the trails, but also wants Crosby to increase its amenities and become the mountain biking equivalent of a ski town. He wants mountain bikers to spend days there, not afternoons. And he wants to create a community so cool that some of those tourists stop being tourists and make the move.
The rest of the town seems to understand听this, too. With the help of a matching grant, a community fundraiser just brought in over $1 million to help expand the trails.
鈥淭hat鈥檚 the biggest thing,鈥 Hautala says. 鈥淵ou can鈥檛 stay status quo to what you were before.鈥 听
