WILLOW, Alaska — By 9:30 most mornings here in the world’s unofficial dog-sledding capital, Luan Marques has harnessed 10 Alaskan huskies to his sled and shot off into the awakening woods for a training ride, his sights set on the famous Iditarod competition next month.

The thick, powdery blanket of snow on the trails and the frigid temperatures have made a musher haven out of Willow, where locals joke that dogs outnumber humans. But as Marques rode this winter, he and his huskies trudged over dirt patches and bramble, surrounded by tree branches that once held fluffy snow. Instead of subzero conditions, which are ideal for the sport, temperatures have been in the 30s and 40s.

“It’s raining and not snowing,” Marques said during a recent training ride, maneuvering the dogs to avoid puddles on the trail. “That’s not good.”

It has made for a trying winter for mushers. Several Iditarod qualifying events have been postponed, rerouted or canceled because of a lack of snow. The John Beargrease sled dog race, a trek of some 400 miles in northern Minnesota, postponed its start to March 10 from Jan. 27. In Alaska, the Don Bowers Memorial 200/300, the Sheep Mountain Lodge 150 and the Knik 200 have been canceled. The Copper Basin 300 in Glennallen, Alaska, had to cut its trail for several teams by 25 miles because there was not enough snow at the finish line; the mushers finished the race with their hats and gloves off and jackets unzipped.
