Tens of thousands of years ago, a glacier slid its way through southern Alaska and carved out the Matanuska-Susitna Valley. Bound by three massive mountain ranges and dotted with lakes, it’s an unabashedly wild place. Hundred-pound cabbages flourish in endless summer sunshine, caribou outnumber people, and towering Denali presides over it all. "You can go 1000 miles here without crossing a road," says Martin Buser. "Most people can’t grasp that kind of freedom." A four-time winner of the Iditarod—the grueling dogsled race from Anchorage to Nome—Buser spends his days crisscrossing the landscape with his dogs. So, for his dream home with his wife, Kathy Chapoton, there was no question that the spectacularly rugged setting needed to be the driving force behind the design.
