North Cascades National Park

North Cascades National Park is a U.S. National Park located in the state of Washington. The park is the largest of the three National Park Service units that comprise the North Cascades National Park Service Complex. Several national wilderness areas and British Columbia parkland adjoin the National Park. The park features rugged mountain peaks and protects portions of the North Cascades range.

Human history

Paleoindians and native Americans

Human history in the region now part of North Cascades National Park dates back to the end of the last glacial period, and the region has been continuously inhabited for at least the last 8-10,000 years. At that time, Native American ancestors of Skagit tribes slowly advanced from Puget Sound into the interior mountainous region as the glacial ice retreated. Archeological evidence of continuous human presence in the North Cascades dates to 4,470 B.P. and rocks procured from sources in the region were used to manufacture stone tools and weapons for several millennia. Hozomeen chert, a type of rock well-suited to the fabrication of implements, was mined from near Hozomeen Mountain, just east of the park border, for the last 8,400 years. Hozomeen chert is part of the archeological record throughout the Skagit River Valley, west of the park and in regions to the east, indicating people visited the region if for no other purpose than to obtain raw materials. Prehistoric micro blades dating back to 9,600 years before present have been discovered at Cascade Pass, a mountain pass that connects the western lowlands to the interior regions of the park and the Stehekin River Valley. The micro blades are part of an archeological assemblage that includes five distinct cultural periods, indicating that people were traveling into the mountains nearly 10,000 years ago. The archeological excavation at Cascade Pass is one of the 260 prehistoric sites that have been identified in the park.

National park

A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.

While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

List of national parks of the United States

The United States has 59 protected areas known as national parks that are operated by the National Park Service, an agency of the Department of the Interior. National parks must be established by an act of the United States Congress. The first national park, Yellowstone, was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks), Sequoia and Yosemite in 1890. The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations." Many current National Parks had been previously protected as National Monuments by the President under the Antiquities Act before being upgraded by Congress. Seven national parks (six in Alaska) are paired with a National Preserve. While administered together, they are considered as separate units and their areas are not included in the figures below. The newest national park is Pinnacles National Park, upgraded in 2013.

North Cascades

The North Cascades are a section of the Cascade Range of western North America. They span the border between the Canadian province of British Columbia and the U.S. state of Washington and are officially named in the U.S. as the Cascade Mountains. The portion in Canada is known as the Canadian Cascades, a designation that also includes the mountains above the east bank of the Fraser Canyon as far north as the town of Lytton, at the confluence of the Thompson and Fraser Rivers.

They are predominantly non-volcanic, but include the stratovolcanoes Mount Baker, Glacier Peak and Coquihalla Mountain, which are part of the Cascade Volcanic Arc.

Geography

The U.S. section of the North Cascades and the adjoining Skagit Range in British Columbia are most notable for their dramatic scenery and challenging mountaineering, both resulting from their steep, rugged topography. While most of the peaks are under 10,000 feet (3,000 m) in elevation, the low valleys provide great local relief, often over 6,000 feet (1,800 m). The summits of the rest of the Canadian Cascades are not glaciated in the same way and feature rock "horns" rising from plateau-like uplands, with the Manning Park and Cathedral Park areas known for their extensive alpine meadows, as is also the case with the eastern flank of the US portion of the range. Portions of the US side of the range are protected as part of North Cascades National Park.

Ecology of the North Cascades

The Ecology of the North Cascades is heavily influenced by the high elevation and rain shadow effects of the mountain range. The North Cascades is a section of the Cascade Range from the South Fork of the Snoqualmie River in Washington, United States, to the confluence of the Thompson and Fraser Rivers in British Columbia, Canada, where the range is officially called the Cascade Mountains but is usually referred to as the Canadian Cascades. The North Cascades Ecoregion is a Level III ecoregion in the Commission for Environmental Cooperation's classification system.

The terrain of the North Cascades is composed of high, rugged mountains. It contains the greatest concentration of active alpine glaciers in the conterminous United States and has a variety of climatic zones. A dry continental climate occurs in the east and mild, maritime, rainforest conditions are found in the west. It is underlain by sedimentary and metamorphic rock in contrast to the adjoining Cascades which are composed of volcanics.
