Every year, Midwestern ski areas are winter fun destinations, but the unusually mild temperatures this winter have left many struggling.

Some resorts have been forced to close runs, or even their entire areas, because of warm temperatures.

Steve Voss, general manager of Sunburst Ski Area in Kewaskum, Wis., said the big storm that went through the Midwest early this winter gave him hope for a great season.

That was until temperatures warmed up again.

“We have the ability to make snow,” Voss said. “But in order to do that, we need cold temperatures.”

Sunburst was closed on a recent weekend because the warm weather prevented the snow guns from producing enough to cover its 11 runs, but Voss said he and the staff are working to open as many runs as possible as soon as they can.

Ski Snowstar Winter Sports Park in Andalusia, Ill., near the Quad Cities, has been open only four days this season, general manager Ed Meyer said.

He said Snowstar has been in operation for 26 years, and this is the first time it has been closed so late in the season.

“We have people on standby every night, and we’re working with a skeleton crew right now,” he said. “We had to cut corners, but I have lots of hope for the rest of the season.”

“It is very disappointing, but there’s still a whole lot of January and February left,” Meyer said.

Other areas have remained open through the entire season, including Cascade Mountain in Portage, Wis.

Eve Direzan, who works the main desk at Cascade, said that while the unusually mild weather has prevented the staff from opening the tubing hill, the resort has been able to make snow several times in recent weeks.

Direzan said Cascade has a base of 20 inches of snow, but she encourages people to continue calling and visiting the area’s Web site for weather and trail information before embarking on a trip there.

“There have been lots of people calling every day,” she said. “Most of the calls we received are people asking about weather conditions.”

Although his ski area has managed to remain open, Joe Vittengl, general manager of Devil’s Head Resort, about 2 hours north of Chicago in Merrimac, Wis., said crowds have been smaller.

Devil’s Head usually greets crowds of anywhere from 2,000 to 3,500 skiers on a good weekend, Vittengl said. But this season, the resort has been lucky to see half that, he said.

Devil’s Head has been able to survive through the warm period, thanks to its snow-making capacities that let the staff “blast the hill,” Vittengl said.

He said 80 percent of Devil’s Head’s runs are open, and he hoped that the colder weather expected this week would create perfect snowmaking conditions.

“We’re lucky to have made it through the warm period,” Vittengl said. “There are quite a few places south of us that were forced to close because they don’t have the snowmaking capacities we do.”

No matter what has happened so far, winter is bound to arrive at some point — unless global warming kicks in a lot sooner than predicted — so there’s no sense putting away your skis and snowboards for good yet.
