Denali's canine rangers connect the past to the present. Sled dogs and rangers continue to work together to protect the wilderness of the park as they have since the 1920s.
The Denali National Park Kennels harnesses the spirit of sled dogs to forge lasting bonds between people and wild places.
In a modern world filled with high tech solutions for "everything", it can be hard to comprehend why we would still actively choose to use traditional dog team travel rather than any of the modern alternatives. In fact, there are many reasons to choose sled dogs.
Denali National Park has had sled dogs since 1922. Read more about the kennels centennial celebrations this year. While 100 years is a long time, in Alaska, sled dogs have been a part of the landscape for many more hundreds of years. Prior to the introduction of mechanized transport, almost every family had a few sled dogs that served as transportation for trapping, trading, and traveling to neighboring villages. Native Alaskans hold generations of knowledge and stories that have contributed to the National Park Service's use of safely and effectively managing sled dogs in Denali's Wilderness.
Our first Superintendent, Harry Karstens, purchased the park's first seven sled dogs for patrolling the newly established park boundaries. The park has maintained working dog teams ever since. Their job has evolved over time and while they are no longer patrolling for poachers, they are still performing essential and inspiring work in protecting and preserving the unique character of Denali.
The dogs, and the kennels where they live, represent important pieces of the American story. These are the only sled dogs in the United States that help protect a national park and the wildlife, scenery, and wilderness therein, and it has been this way since the birth of our Park.
ReliabilitySled dogs have hearts and brains that machines such as snowmobiles and airplanes do not. Every kennels ranger has a story of wise lead dogs helping them navigate to a patrol cabin in a white out or to avoid dangerous ice obscured under snow. The dogs know this landscape well and they can provide invaluable wisdom that machines cannot. While a team of sled dogs is obviously far slower than an airplane or a snowmobile, they are arguably more reliable to operate in the extreme conditions of a sub-arctic winter.
At 40 below zero, it can be near impossible to try to start a motor, whereas a dog team simply needs a good breakfast and they are ready and willing to run. Overflow is a common challenge on rivers and trails in Denali. Snowmobiles can get bogged down and sink in this slushy mess whereas a dog team can run right through it and roll in the snow to dry off on the other side. If a machine breaks down in the middle of remote wilderness like Denali, you had better hope you are carrying the right spare parts and tools to fix it! However, if a sled dog gets sick or injured on the trail, you can always rely on the rest of the team to pull the sled while the injured dog can run loose or ride in the sled until they have recovered.
Similar to summer’s backcountry rangers, kennels rangers on dogsleds contact winter recreationists and provide information on trail conditions, offer assistance, and monitor use in a low-impact style that preserves the wilderness spirit essential to Denali. The sled-dog trails made during winter field operations are used by winter recreationists who want to explore Denali on skis, snowshoes, or with their own dog team. In winter (November–April), you can use the map at the bottom of this page to track the travels of the NPS sled dogs and get updates on current conditions throughout the park.
Federally Designated Wilderness
There are over 2 million acres of designated Wilderness in Denali. This is the highest level of federal protection for public lands and the sled dogs of Denali play a huge role in protecting and preserving the unique wilderness character of this park.
