National Park - Alaska
Kobuk Valley National Park is in the Arctic region of northwestern Alaska, located about 25 miles (40 km) north of the Arctic Circle. The park preserves the 100 ft (30 m) high Great Kobuk Sand Dunes and the surrounding area which includes caribou migration routes. Park visitors must bring all their own gear for backcountry camping, hiking, backpacking, boating, and dog sledding. The park is one of the least-visited American national parks. Since no designated trails or roads exist in the park, visitors arrive via chartered air taxi from Nome, Bettles, or Kotzebue. Flights are available year-round, but are weather dependent.

Caribou, sand dunes, the Kobuk River, Onion Portage - just some of the facets of Kobuk Valley National Park. Half a million caribou migrate through, their tracks crisscrossing sculpted dunes. The Kobuk River is an ancient and current path for people and wildlife. For 9000 years, people came to Onion Portage to harvest caribou as they swam the river. Even today, that rich tradition continues. Kobuk Valley National Park is very remote. There are no roads to provide access, so planes take care of most transportation needs. Commercial airlines provide service from Anchorage to Kotzebue, or from Fairbanks to Bettles. Once in Kotzebue or Bettles, you must fly to the park with authorized air taxis. Northwest Arctic Heritage Center Large, half-dome shaped, blue and grey building with just over 11,000 square feet of space. The museum space is just over 1,800 square feet and contains animal displays, soundscapes, tactile exhibits and more. The Heritage Center also contains a bookstore, restroom, art gallery, and sitting area. The Northwest Arctic Heritage Center serves as the visitor centers for the Western Arctic National Parklands: Kobuk Valley National Park, Cape Krusenstern National Monument, and Noatak National Preserve. Visitors generally access the park via the regional hub in Kotzebue. Commercial airlines provide daily service from Fairbanks or Anchorage, to Kotzebue. Chartered flights with licensed air taxi services, booked in advance, can take backcountry travelers to remote destinations within the park.

Permafrost Resource Brief for the Arctic Network Permafrost underlies most of the Arctic Network and affects nearly everything in the arctic ecosystem. Thawing permafrost also changes the local hydrology and creates the second-greatest disturbance to boreal forests, after wildfires. Recent warm and wet conditions caused some thaw of ice masses and surface subsidence in Arctic parks that ultimately led to a record number of drained of shallow lakes. This brief provides an update on permafrost monitoring in the Arctic Network Polygonal shaped tundra due to underlying permafrost Arctic Cryosphere: snow, water, ice, and permafrost This article is a summary of findings from the Snow, Water, Ice, and Permafrost in the Arctic report by the Arctic Council Arctic Monitoring and Assessment Programme.

Subsistence The study of subsistence resources in parks has been a mix of long-term work and projects instigated by issues facing the Federal Subsistence Board. Winter hunting is an important subsistence activity in many Alaska communities and park areas. Alaska Native Place Names in Arctic Parks Indigenous place names are rich ethnographic and historical resources. Many of them refer to activities that regularly took place at the site; others tell of historical events that occurred there. These names have been replaced by English names on modern maps; this article discusses efforts to document these names into the future. a group of people near a canvas tent, alongside a large river Red Fox Despite the name, red foxes come in a variety of colors.

Recorded paleontological discoveries were made in the immediate area as early as 1816. However, the region has lacked the level of attention and scientific study of other northern areas such as the Klondike and the Yukon, and is therefore lesser known. woman standing to a waist-high leg bone What Future for the Wildness of Wilderness in the Anthropocene? Visionary as it was, the Wilderness Act did not anticipate today’s human-driven, global-scale changes. The idea of preserving wild lands challenges us with the irony that such places, untouched by humans, will only continue through our will to keep them that way. A resolute human purpose is needed to maintain the decision to have areas that are free of human purpose. aerial view of wolves moving single-file through a snowy forest The Economic and Cultural Benefits of Northwest Alaska Wilderness Northwest Alaska, from Kotzebue Sound to the headwaters of the Kobuk River, is approximately the size of Indiana. It is mostly roadless wild lands, dotted by eleven villages that are located on the coast or major rivers. The formal designation of wilderness areas in northwest Alaska contributes to sustaining an ecosystem that is predicated on an expansive area of natural habitat that is not fragmented by human development. four caribou swimming in neck-deep water Alaska Aviation Safety In Alaska, small planes are often the best way to get around but flying has its risks.

In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era. fossil corals in a rock matrix Fire Extent and Frequency Resource Brief for the Arctic Network Fire affects all 5 parks within the Arctic Network. The first fires in the network were officially recorded in 1956, although the history of fire in these parks, based on charcoal records dates back to at least 6,000 years ago. Since 1956, 574 fires have occurred in Arctic Network parks, burning nearly 1.1 million acres, an area almost twice the size of Cape Krusenstern National Monument. The vast majority of these fires (97%) were started by lightning. Fire ecologist measures depth of soil consumption in tussocks 1 year after a recent fire in Noatak. Fire in Ecosystems: Boreal Forest The boreal forest, also called taiga, is the largest forested habitat in the world, making up one third of the earth’s total forested area. In North America, the boreal forest spreads from Alaska, across Canada, and into the Great Lakes region of the United States. Boreal forests have burned naturally for thousands of years creating a variety of landscapes, or mosaic, with young and old trees living on the landscape. Aerial view of flaming front in coniferous trees putting off a lot of smoke. Shallow Lakes Resource Brief for the Arctic Network Currently, lakes in the parks of the Arctic Network are being negatively affected by climate warming—lake surface area has significantly declined since the 1980’s due to warming temperatures, and rapid change has happened over the last five years. Lakes and wetlands are often referred to as the “kidneys of the landscape” because they clean the water by trapping sediment, nutrients, and organic material like leaves. Every year we visit six continuous monitoring lakes. a biologist in a bug jacket walks a lake margin recording vegetation data. Brown Bear Resource Brief for the Arctic Network Alaska has more than 50% of the remaining North American brown bears and the second largest population worldwide. Parks in the Arctic Inventory and Monitoring Network may ultimately provide a refuge for brown bears in northwest Alaska that are adapted to life in the Arctic, but strong monitoring programs are needed to understand whether these bear populations can remain healthy in a rapidly changing Arctic.

Muskox lying on tundra with a mountain in the background under overcast sky Terrestrial Vegetation and Soils Resource Brief for the Arctic Network Vegetation is the basis for ecosystem productivity and wildlife habitat. Arctic vegetation is very sensitive to climate change and disturbance such as fire, herbivory, and traffic. Research has documented an increase in shrubs and, to a lesser extent, trees in the arctic over recent decades, probably related to climate change.
