The pups are born in the kennel, and staff are always on hand 00:04:24.515 --> 00:04:28.060 to assist with the arrival of the newest canine rangers. 00:04:29.000 --> 00:04:33.500 [music] 00:04:33.500 --> 00:04:35.500 For the first few weeks of their lives, 00:04:35.567 --> 00:04:37.736 the pups are entirely dependent on mom. 00:04:39.236 --> 00:04:43.600 Their eyes and ears remain closed, and they can't produce their own body heat 00:04:43.659 --> 00:04:45.118 or eliminate their own waste. 00:04:47.100 --> 00:04:49.081 They spend all of their time sleeping, 00:04:49.081 --> 00:04:50.499 nursing, and growing. 00:04:54.100 --> 00:04:58.100 After the first critical weeks have passed, the pups emerge from the doghouse 00:04:58.131 --> 00:05:00.342 and begin to explore their world. 00:05:03.000 --> 00:05:06.400 Kennels rangers handle and gently stress each pup, 00:05:06.473 --> 00:05:09.393 developing essential neuromotor pathways. 00:05:12.300 --> 00:05:15.300 This allows them to calmly react to any situation 00:05:15.524 --> 00:05:17.651 they may face in their adult lives. 00:05:24.100 --> 00:05:29.000 As the pups grow, training starts to build sled dog skills. 00:05:29.000 --> 00:05:32.500 Short runs on the track turn to long, exploratory walks 00:05:32.500 --> 00:05:35.300 with the rangers, mom and other adult dogs. 00:05:35.300 --> 00:05:38.000 The pups run through the woods, 00:05:38.000 --> 00:05:40.000 climb over logs, 00:05:40.000 --> 00:05:42.700 and get their feet wet at creek crossings, 00:05:42.700 --> 00:05:45.000 all preparing them for the challenges of the trail 00:05:45.000 --> 00:05:47.000 Truly important, 00:05:47.000 --> 00:05:49.100 as these pups will replace the kennel's oldest dogs, 00:05:49.100 --> 00:05:52.000 who at age 9 are ready for retirement. 00:05:52.000 --> 00:05:55.600 But it's not just the pups who are training each fall— 00:05:55.600 --> 00:05:58.100 kennels rangers have to get the big dogs ready 00:05:58.150 --> 00:06:00.235 for the trail too. 00:06:04.698 --> 00:06:14.000 [upbeat music] 00:06:14.000 --> 00:06:15.000 Getting in shape for winter work 00:06:15.083 --> 00:06:17.461 begins with cart and ATV runs. 00:06:20.100 --> 00:06:22.400 When there's enough snow, we switch to sleds, 00:06:22.591 --> 00:06:25.177 and that's when the fun really begins. 00:06:25.177 --> 00:06:29.300 [music] 00:06:29.300 --> 00:06:31.700 During these runs, each dog not only rebuilds 00:06:31.700 --> 00:06:33.700 physical strength and fitness, 00:06:33.700 --> 00:06:36.300 but also sharpens his or her mental capacity 00:06:36.300 --> 00:06:38.300 for team work, navigation 00:06:38.300 --> 00:06:40.600 and the ability to follow commands. 00:06:40.692 --> 00:06:42.152 - Come on! Let's go! 00:06:45.100 --> 00:06:47.100 By the time the snow starts to blanket 00:06:47.100 --> 00:06:49.100 the pristine Denali landscape, 00:06:49.100 --> 00:06:51.100 the new puppies have grown big enough to cover 00:06:51.100 --> 00:06:53.100 several miles running loose, 00:06:53.100 --> 00:06:55.100 but they are still not physically 00:06:55.100 --> 00:06:57.100 or mentally ready to train and pull 00:06:57.100 --> 00:06:59.100 with the adult dogs. 00:06:59.545 --> 00:07:02.005 The pups learn to pull by skijoring. 00:07:03.505 --> 00:07:05.000 Pulling a skier 00:07:05.000 --> 00:07:07.000 is a much less stressful way 00:07:07.000 --> 00:07:09.000 for the pups to learn the concept of pulling, 00:07:09.000 --> 00:07:11.000 and can accomplish several goals. 00:07:13.000 --> 00:07:15.200 We can have one adult dog on the line 00:07:15.227 --> 00:07:17.688 to help guide the puppy and show her what to do. 00:07:19.100 --> 00:07:21.600 We can work individually with the little guys on verbal commands 00:07:21.600 --> 00:07:24.000 and build their confidence in working with humans. 00:07:25.500 --> 00:07:27.000 The puppies love skijoring, 00:07:27.000 --> 00:07:28.700 and it gives us great insight 00:07:28.700 --> 00:07:30.700 into each individual's personality 00:07:30.700 --> 00:07:33.600 and their training needs, much more so than if they were just 00:07:33.662 --> 00:07:35.873 one of many dogs pulling in a team. 00:07:41.000 --> 00:07:43.100 The park's modern day mushers and dogs 00:07:43.100 --> 00:07:45.100 carry on a long, proud tradition 00:07:45.100 --> 00:07:47.100 of human and canine rangers working together 00:07:47.100 --> 00:07:50.200 to travel and protect this unique landscape. 00:07:50.900 --> 00:07:53.500 Harry Karstens, the park's original superintendent 00:07:53.500 --> 00:07:55.500 was first and foremost a dog musher. 00:07:57.000 --> 00:07:59.000 Even before the park was established, 00:07:59.000 --> 00:08:01.500 Karstens traveled and worked in the area, 00:08:01.500 --> 00:08:03.900 most notably as a guide for Charles Sheldon, 00:08:03.900 --> 00:08:05.900 a wealthy hunter-naturalist 00:08:05.900 --> 00:08:07.900 who came to study Dall sheep in the early 1900s. 00:08:09.900 --> 00:08:12.100 This partnership and journey inspired Sheldon 00:08:12.100 --> 00:08:14.600 to lobby for the creation of this national park 00:08:14.600 --> 00:08:16.600 in 1917. 00:08:16.600 --> 00:08:20.000 When Superintendent Karstens was first tasked with protecting the park, 00:08:20.000 --> 00:08:23.500 he recognized a dog team was essential to his duties. 00:08:23.500 --> 00:08:25.500 He bought the park's first seven sled dogs 00:08:25.500 --> 00:08:27.500 from Norman Hadley in Nenana 00:08:27.500 --> 00:08:29.700 and used the team to monitor wildlife 00:08:29.718 --> 00:08:31.595 and patrol for poachers. 00:08:35.600 --> 00:08:38.900 A century later, the dogs have proven an invaluable tool 00:08:38.900 --> 00:08:40.900 for traveling Denali's remote landscapes, 00:08:40.900 --> 00:08:43.900 even in today's rapidly changing modern times. 00:08:47.000 --> 00:08:50.000 Dog teams remain more reliable than most machines 00:08:50.000 --> 00:08:52.300 when it comes to starting up at 50 below zero. 00:08:52.533 --> 00:08:53.534 [engine rumbling] 00:08:54.500 --> 00:08:56.500 They can easily travel through wet overflow, 00:08:57.000 --> 00:08:59.500 a hazard that could bog down a snowmobile. 00:09:04.000 --> 00:09:06.300 By using these sled dogs instead of machines, 00:09:06.300 --> 00:09:09.600 we're replacing cold engines with warm, beating hearts. 00:09:10.467 --> 00:09:14.012 We're trading a tangle of wires for a network of veins, 00:09:15.000 --> 00:09:18.000 channeling blood enriched with passion, purity, 00:09:18.000 --> 00:09:22.100 and an electricity that no battery will ever come close to harnessing. 00:09:23.272 --> 00:09:25.399 That's what powers this place. 00:09:27.900 --> 00:09:31.000 And after a long day on the trail, 00:09:31.000 --> 00:09:33.400 dogs are much more fun to cuddle up with 00:09:33.448 --> 00:09:35.117 than any snowmobile. 00:09:38.500 --> 00:09:40.200 These sled dogs can also go 00:09:40.289 --> 00:09:42.165 where machines legally cannot... 00:09:45.000 --> 00:09:47.500 The two million acres of Denali wilderness 00:09:47.546 --> 00:09:50.799 established during the park's expansion in 1980. 00:09:52.400 --> 00:09:56.000 Wilderness, as defined by the Wilderness Act of 1964, 00:09:56.000 --> 00:09:58.500 is a place where the land is untouched 00:09:58.557 --> 00:10:02.394 and man himself is a visitor who does not remain. 00:10:05.000 --> 00:10:08.300 Wilderness is so much more than s set of legal directives. 00:10:08.300 --> 00:10:10.700 It is also an experience, 00:10:11.500 --> 00:10:15.000 a feeling our visitors are seeking when they come here. 00:10:15.700 --> 00:10:18.300 The sled dogs are an exceptional means 00:10:18.300 --> 00:10:21.900 of preserving the unique wilderness character of this park. 00:10:23.000 --> 00:10:26.500 By using them as our primary means of transport in the winter, 00:10:27.000 --> 00:10:29.700 we keep our heritage alive and promote the value 00:10:29.713 --> 00:10:33.133 of traditional tools and skills in a modern world. 00:10:33.133 --> 00:10:39.500 [music] 00:10:39.500 --> 00:10:46.000 [wind blowing] 00:10:46.000 --> 00:10:47.481 — We're getting ready to go check out 00:10:47.481 --> 00:10:49.983 the lower stakes on the Traleika Glacier. 00:10:52.000 --> 00:10:54.000 These stakes were drilled into the ice, 00:10:54.000 --> 00:10:56.000 and we periodically go out and see 00:10:56.000 --> 00:10:58.000 how much they've melted out of the ice, 00:10:58.000 --> 00:10:59.701 and do a couple other things, 00:10:59.701 --> 00:11:02.204 like check out the snow density. 00:11:03.000 --> 00:11:04.700 What makes these stakes really interesting, 00:11:04.700 --> 00:11:06.700 or monitoring this glacier particularly 00:11:06.700 --> 00:11:08.900 really interesting, is that over the past year 00:11:08.900 --> 00:11:10.900 the elevation of the glacier has actually been rising, 00:11:10.900 --> 00:11:14.700 which makes it seem like something's going on, 00:11:14.716 --> 00:11:16.093 like it might be surging. 00:11:18.000 --> 00:11:20.000 During Denali's long, cold winter, 00:11:20.000 --> 00:11:23.000 park scientists may need to access remote locations 00:11:23.000 --> 00:11:25.200 within designated Wilderness for their research, 00:11:25.200 --> 00:11:27.500 or trail crew and maintenance staff 00:11:27.500 --> 00:11:29.700 may need to transport large, bulky items 00:11:29.731 --> 00:11:32.109 to remote locations for project work. 00:11:34.500 --> 00:11:38.500 While a helicopter, airplane or snowmobile may seem like the obvious choice, 00:11:38.500 --> 00:11:40.325 the Wilderness Act mandates 00:11:40.325 --> 00:11:42.619 park staff take a different approach. 00:11:44.500 --> 00:11:47.000 — You know, the dogs mushed out to Wonder Lake 00:11:47.000 --> 00:11:48.834 and then the dogs actually hauled all of our stuff 00:11:48.834 --> 00:11:50.294 up to McGonagall pass. 00:11:52.000 --> 00:11:53.500 Park managers must ask, 00:11:53.500 --> 00:11:56.900 "What is the minimum tool that we can use for this job?" 00:11:58.000 --> 00:11:59.900 In Denali, that means asking, 00:11:59.928 --> 00:12:02.556 "Can we use a dog team to accomplish this work?" 00:12:02.556 --> 00:12:04.900 [wind blowing] 00:12:04.900 --> 00:12:08.600 Dog teams don't just haul in supplies to remote locations. 00:12:08.645 --> 00:12:11.398 They also haul materials out of wilderness. 00:12:12.100 --> 00:12:14.900 Backcountry rangers and volunteers 00:12:14.900 --> 00:12:16.900 will hike into remote areas 00:12:16.900 --> 00:12:19.400 and pile up heavy debris during the summer months 00:12:19.400 --> 00:12:21.800 so that dog teams can return in winter 00:12:21.825 --> 00:12:23.285 to haul it out. 00:12:23.285 --> 00:12:27.200 [music] 00:12:27.200 --> 00:12:30.000 In addition to the projects completed with other divisions, 00:12:30.000 --> 00:12:34.000 we also help break trail and establish winter travel routes. 00:12:35.000 --> 00:12:36.700 We report on conditions 00:12:36.700 --> 00:12:39.100 and help our winter visitors prepare for the backcountry. 00:12:40.000 --> 00:12:41.300 And in doing that, 00:12:41.300 --> 00:12:43.900 we hope our dog teams encourage and inspire people 00:12:43.900 --> 00:12:45.474 to come and have their own adventures 00:12:45.474 --> 00:12:48.018 during Denali's beautiful winter season. 00:12:48.018 --> 00:12:50.200 [music] 00:12:50.200 --> 00:12:52.500 Most summer visitors cannot imagine 00:12:52.500 --> 00:12:54.500 returning to Denali in winter, 00:12:54.500 --> 00:12:57.000 but kennels rangers have long known a secret 00:12:57.000 --> 00:12:58.700 that surprises many: 00:12:59.500 --> 00:13:01.800 travel in this park is often easier 00:13:01.865 --> 00:13:04.284 when the thermometer dips below zero. 00:13:05.784 --> 00:13:08.100 Thick brush hides beneath swales of snow, 00:13:10.100 --> 00:13:12.500 boggy lakes and spongy tundra freeze solid, 00:13:13.500 --> 00:13:15.800 and turbulent rivers transform 00:13:15.838 --> 00:13:17.923 into highways of ice. 00:13:20.000 --> 00:13:23.100 For those seeking solitude, adventure and challenge, 00:13:23.100 --> 00:13:26.000 a winter journey through Denali's wilderness 00:13:26.000 --> 00:13:27.900 provides the intrepid traveler 00:13:27.900 --> 00:13:30.400 a refuge from modern civilization 00:13:30.435 --> 00:13:33.063 and a place to rejuvenate the spirit. 00:13:34.000 --> 00:13:37.500 Cold temperatures typically usher in clear, sunny skies, 00:13:37.500 --> 00:13:40.000 which reward with gorgeous views 00:13:40.000 --> 00:13:42.000 of the majestic Alaska Range, 00:13:43.000 --> 00:13:46.600 and long, dark winter nights provide opportunities 00:13:46.618 --> 00:13:50.414 to witness the magic of the Aurora Borealis. 00:13:50.414 --> 00:14:01.000 [music] 00:14:01.000 --> 00:14:03.000 But don't be fooled— 00:14:03.000 --> 00:14:05.000 the relative ease of 00:14:05.000 --> 00:14:07.000 travel and the breathtaking beauty of Denali in winter 00:14:07.000 --> 00:14:09.000 does not mean the work we do is easy. 00:14:09.700 --> 00:14:11.000 If you think that dog mushing is about 00:14:11.000 --> 00:14:13.000 standing on the runners on the back of the sled 00:14:13.000 --> 00:14:15.000 and enjoying the view, 00:14:15.000 --> 00:14:17.000 think again. 00:14:17.000 --> 00:15:04.000 [music] 00:15:04.000 --> 00:15:06.000 No matter the conditions, 00:15:06.000 --> 00:15:08.000 after a long, hard day on the trail, 00:15:08.000 --> 00:15:10.000 both mushers and dogs are happy 00:15:10.000 --> 00:15:11.800 to reach a cabin for the night ... 00:15:13.100 --> 00:15:14.700 ... even if the work does not end 00:15:14.790 --> 00:15:16.708 when they reach their destination. 00:15:20.100 --> 00:15:23.900 Feeding and hydrating 30 to 35 hard-working dogs on the trail 00:15:23.966 --> 00:15:25.884 is no small task. 00:15:28.000 --> 00:15:31.400 After the mushers have finished their chores, a couple of lucky dogs 00:15:31.473 --> 00:15:34.768 are chosen to join them in the cabin for some extra attention. 00:15:37.300 --> 00:15:40.000 When everyone has had their fill of belly rubs and play, 00:15:40.000 --> 00:15:42.000 it is time to rest. 00:15:42.900 --> 00:15:44.900 Tomorrow will be another busy day. 00:15:45.404 --> 00:15:47.656 This is life on the trail. 00:15:47.656 --> 00:15:56.000 [music] 00:15:56.000 --> 00:15:58.000 As the season goes on, 00:15:58.000 --> 00:16:00.000 the dog teams travel 00:16:00.000 --> 00:16:01.378 deep into the heart of the wilderness, 00:16:01.378 --> 00:16:04.339 beyond where any patrol cabins exist. 00:16:05.839 --> 00:16:08.700 There's something very soothing and rewarding 00:16:08.700 --> 00:16:10.700 about performing the basic tasks 00:16:10.700 --> 00:16:12.700 required to survive. 00:16:13.000 --> 00:16:15.000 Everything gets distilled down 00:16:15.500 --> 00:16:18.100 to food, water, shelter and warmth. 00:16:19.100 --> 00:16:22.000 In our high-tech, fast-paced, modern world 00:16:22.065 --> 00:16:24.484 we treasure the gift of slowing down... 00:16:27.237 --> 00:16:29.740 And remembering the simple pleasures... 00:16:32.000 --> 00:16:34.300 We all find great joy and satisfaction 00:16:34.300 --> 00:16:36.700 in days consumed by the simple acts 00:16:36.788 --> 00:16:39.333 of travel and work in wilderness. 00:16:42.500 --> 00:16:45.500 By this point, the adult dogs are in peak condition 00:16:45.500 --> 00:16:48.000 and can easily travel 30 or more miles per day, 00:16:48.000 --> 00:16:49.885 hauling more equipment 00:16:49.885 --> 00:16:52.221 and completing more project work. 00:16:53.500 --> 00:16:56.500 Last summer's pups are also bigger and better by March. 00:16:58.500 --> 00:17:01.000 They've spent the winter running loose next to the teams, 00:17:01.000 --> 00:17:03.300 and have learned the common travel routes, 00:17:03.300 --> 00:17:06.500 experienced various trail conditions, 00:17:06.527 --> 00:17:09.238 and burned off some of their puppy energy. 00:17:10.500 --> 00:17:13.500 Physically, the pups are still not ready to pull the sleds 00:17:13.500 --> 00:17:15.500 for more than a few short miles, 00:17:15.500 --> 00:17:19.500 but, they'll continue to grow and get stronger, 00:17:19.500 --> 00:17:21.500 so by next fall, 00:17:21.500 --> 00:17:24.586 they will be ready to run with the big dogs. 00:17:26.000 --> 00:17:31.500 [music] 00:17:31.500 --> 00:17:34.300 Saying goodbye to winter and hello to spring 00:17:34.304 --> 00:17:36.765 feels bittersweet for the kennel staff. 00:17:36.765 --> 00:17:40.100 [water dripping and flowing] 00:17:40.100 --> 00:17:42.100 As temperatures warm 00:17:42.100 --> 00:17:43.900 and the land prepares for summer, 00:17:43.900 --> 00:17:45.315 rangers store heavy parkas, 00:17:45.315 --> 00:17:47.860 harnesses, and sleds for another year. 00:17:49.900 --> 00:17:52.000 Only memories of the winter remain, 00:17:52.000 --> 00:17:54.500 and soon another season begins. 00:17:56.000 --> 00:17:58.500 The rangers will be busy answering questions 00:17:58.500 --> 00:18:00.500 and giving demonstrations 00:18:00.500 --> 00:18:02.000 to thousands of visitors, 00:18:02.000 --> 00:18:04.000 while the dogs rest on their houses. 00:18:04.000 --> 00:18:06.000 [music] 00:18:06.000 --> 00:18:08.000 Visitors will scratch behind their ears, 00:18:08.000 --> 00:18:10.000 rub their bellies, and stare into 00:18:10.000 --> 00:18:11.300 the dogs' eyes, 00:18:11.925 --> 00:18:15.429 perhaps catching a glimmer of their winter adventures. 00:18:15.429 --> 00:18:17.429 [music] 00:18:17.429 --> 00:18:19.429 The sled dogs offer them a connection 00:18:19.429 --> 00:18:21.429 to a different world, 00:18:22.311 --> 00:18:24.897 a fearsome and fragile wilderness. 00:18:24.897 --> 00:18:28.200 [music] 00:18:28.200 --> 00:18:30.200 It is not hard to understand 00:18:30.200 --> 00:18:32.200 why the canine and human rangers 00:18:32.200 --> 00:18:34.200 are so passionate about their work, 00:18:35.200 --> 00:18:37.400 why they are willing to go to such great lengths 00:18:37.451 --> 00:18:39.536 to protect this great land. 00:18:41.536 --> 00:18:43.536 These sled dogs teach us to 00:18:43.536 --> 00:18:45.536 pursue our daily lives and work 00:18:45.536 --> 00:18:48.000 with unbridled enthusiasm and dedication. 00:18:49.300 --> 00:18:51.548 We wholeheartedly share in their desire 00:18:51.548 --> 00:18:53.467 to run and explore... 00:18:55.467 --> 00:18:58.500 ... to see what lies beyond the next bend in the river ... 00:18:59.681 --> 00:19:02.267 ... or over the next mountain range. 00:19:05.000 --> 00:19:07.400 And while it is a unique relationship 00:19:07.400 --> 00:19:09.400 that exists between ranger and sled dog, 00:19:11.000 --> 00:19:13.000 the Denali dogs should hold a special place 00:19:13.070 --> 00:19:15.113 in each of our hearts. 00:19:15.113 --> 00:19:19.500 [music] 00:19:19.500 --> 00:19:22.000 We live in a rapidly changing world 00:19:22.000 --> 00:19:24.000 where ice caps are melting 00:19:24.000 --> 00:19:26.500 and Alaska's winters are warming, 00:19:28.000 --> 00:19:30.500 where daily life revolves around technology 00:19:31.300 --> 00:19:33.173 and the simple pleasures of nature 00:19:33.173 --> 00:19:35.092 can be hard to find. 00:19:37.092 --> 00:19:39.092 By doing what they love 00:19:39.092 --> 00:19:40.900 and taking on the work of the park, 00:19:40.900 --> 00:19:42.900 the Denali sled dogs lead the way 00:19:42.900 --> 00:19:44.900 in preserving and protecting 00:19:44.900 --> 00:19:46.500 the integrity of this wild place. 00:19:48.000 --> 00:19:50.300 They also remind us of our responsibility 00:19:50.315 --> 00:19:52.067 to future generations: 00:19:54.067 --> 00:19:56.067 That we must act to ensure 00:19:56.067 --> 00:19:57.500 our children and grandchildren 00:19:57.500 --> 00:19:59.500 have the same opportunities 00:19:59.500 --> 00:20:02.500 for discovery, adventure, reflection 00:20:02.500 --> 00:20:04.800 and solitude in this park 00:20:04.830 --> 00:20:07.541 and its great, vast wilderness. 00:20:07.541 --> 00:21:13.200 [music]
