Rocky Mountain National Park

Rocky Mountain National Park is a national park of the United States located approximately 55 mi (89 km) northwest of Denver^[5] in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and western slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region.^[6] The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra.

The Rocky Mountain National Park Act was signed by President Woodrow Wilson on January 26, 1915, establishing the park boundaries and protecting the area for future generations.^[3] The Civilian Conservation Corps built the main automobile route, Trail Ridge Road, in the 1930s.^[3] In 1976, UNESCO designated the park as one of the first World Biosphere Reserves.^[7] In 2023, 4.1 million recreational visitors entered the park.^[8] The park is one of the most visited in the National Park System, ranking as the third most visited national park in 2015.^[9] In 2019, the park saw record attendance yet again with 4,678,804 visitors, a 44% increase since 2012.^[10]

The park has five visitor centers,^[11] with park headquarters located at the Beaver Meadows Visitor Center—a National Historic Landmark designed by the Frank Lloyd Wright School of Architecture at Taliesin West.^[12] National Forest lands surround the park on all sides, including Roosevelt National Forest to the north and east, Routt National Forest to the north and west, and Arapaho National Forest to the west and south, with the Indian Peaks Wilderness area located directly south of the park.^[6]

The history of Rocky Mountain National Park began when Paleo-Indians traveled a route near what is now Trail Ridge Road to hunt and forage for food.^[13] Ute and Arapaho people subsequently hunted and camped in the area.^[14][15] In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River.^[16][17] Settlers began arriving in the mid-1800s,^[18] displacing the Native Americans by 1878.^[15]

Lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver.^[19] The boom ended by 1883 with miners deserting their claims.^[20] The railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U.S. Route 34 from Loveland to Estes Park—was completed in 1904.^[21] The 1920s saw a boom in building lodges, including the Bear Lake Trail School, and roads in the park, culminating with the construction of Trail Ridge Road to Fall River Pass between 1929 and 1932, then to Grand Lake by 1938.^[22]

Prominent individuals in the effort to create a national park included Enos Mills from the Estes Park area, James Grafton Rogers from Denver, and J. Horace McFarland of Pennsylvania.^[23] The national park was established on January 26, 1915.^[3]

Rocky Mountain National Park encompasses 265,461 acres (414.78 sq mi; 1,074.28 km²) of federal land,^[2] with an additional 253,059 acres (395.40 sq mi; 1,024.09 km²) of U.S. Forest Service wilderness adjoining the park boundaries.^[24] The Continental Divide runs generally north–south through the center of the park,^[25] with rivers and streams on the western side of the divide flowing toward the Pacific Ocean while those on the eastern side flow toward the Atlantic.^[26]

A geographical anomaly is found along the slopes of the Never Summer Mountains where the Continental Divide forms a horseshoe–shaped bend for about 6 miles (9.7 km), heading from south–to–north but then curving sharply southward and westward out of the park.^[6][27] The sharp bend results in streams on the eastern slopes of the range joining the headwaters of the Colorado River that flow south and west, eventually reaching the Pacific.^[6][28] Meanwhile, streams on the western slopes join rivers that flow north and then east and south, eventually reaching the Atlantic.^[6][28]

The headwaters of the Colorado River are located in the park's northwestern region.^[25] The park contains approximately 450 miles (724 km) of rivers and streams, 350 miles (563 km) of trails, and 150 lakes.^[25][29]

Rocky Mountain National Park is one of the highest national parks in the nation, with elevations from 7,860 to 14,259 feet (2,396 to 4,346 m),^[30] the highest point of which is Longs Peak.^[31] Sixty mountain peaks over 12,000 feet (3,658 m) high provide scenic vistas.^[30] On the north side of the park, the Mummy Range contains a number of thirteener peaks, including Hagues Peak, Mummy Mountain, Fairchild Mountain, Ypsilon Mountain, and Mount Chiquita.^[32] Several small glaciers and permanent snowfields are found in the high mountain cirques.^[33]

Baker Pass crosses the Continental Divide through the Never Summer Mountains and into the Michigan River drainage to the west of Mount Nimbus^[34]—a drainage that feeds streams and rivers that drain into the Gulf of Mexico.^[35] Other mountain passes are La Poudre Pass and Thunder Pass, which was once used by stage coaches and is a route to Michigan Lakes.
