More: Nutmeg is part of a 100 year history of working dogs in Denali National Park, and sled dogs have been part of the Alaska landscape for many more hundreds of years. Sled dogs have hearts and brains that machines such as snowmobiles and airplanes do not. Stories of wise lead dogs helping navigate to a patrol cabin in a white out, or avoiding dangerous ice under snow are common. These days, Nutmeg shows the same enthusiasm for walks, and naps on the couch as she once did for patrolling in the park.
