Human history in North Cascades National Park and the surrounding region begins 8–10,000 years ago, after the end of the last glacial period. Human history Paleoindians and Native Americans Mountaineering is popular in the park and only unobtrusive clean climbing is allowed. ![]() Camping inside the park requires hiking in by trail, horseback or boat, and camping is regulated by a permit system to ensure the wilderness is not over-exploited. Visitors wishing to drive to a campground must do so in the adjacent national forests or national recreation areas. North Cascades National Park is almost entirely protected as wilderness, and so the park has few structures, roads or other improvements. The park has one of the earliest and longest lasting research programs dedicated to studying climate change, primarily through examining the effects of glacial retreat. Most of the plant and animal species native to the park region are still found there, though climate change and pollutants from industrialized regions to the west pose risks to the environment. Most access to the park is from State Route 20, which follows the Skagit River, though even this road is closed for months at a time in the winter. Heavy snows and a high risk of avalanches due to the steep terrain, especially on the western slopes, severely limit visitation in the winter. Environmentalists then campaigned to preserve the remaining wilderness, culminating on October 2, 1968, with the designation of North Cascades National Park. The first significant human impact in the region occurred in the 1920s when several dams were built in the Skagit River valley to generate hydroelectric power. Limited mining and logging occurred from the late 19th century to the early 20th century. After the Canada–United States border was set at the 49th parallel in 1846, explorers came to chart potential routes through the mountains for roads and railroads. By the early 19th century, the region was visited by fur trappers and several British and American companies vied for control over the fur trade. ![]() The region was first settled by Paleo-Indian Native Americans by the time European American explorers arrived, it was inhabited by Skagit tribes. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through the reservoirs of Ross Lake National Recreation Area. At more than 500,000 acres (200,000 ha), it is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park is an American national park in the state of Washington. Location in the United States Show map of the United States
