The National Parks

Situated on the Yellowstone Caldera, the park has an expansive network of geothermal areas including boiling mud pots, vividly colored hot springs such as Grand Prismatic Spring, and regularly erupting geysers, the best-known being Old Faithful. The yellow-hued Grand Canyon of the Yellowstone River contains several high waterfalls, while four mountain ranges traverse the park. More than60 mammal species including gray wolves, grizzly bears, black bears, lynxes, bison, and elk, make this park one of the best wildlife viewing spots in the country. Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the Continental United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in the park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational... Read More

This park and the co-managed state parks protect almost half of all remaining coastal redwoods, the tallest trees on earth. There are three large river systems in this very seismically active area, and 37 miles (60 km) of protected coastline reveal tide pools and seastacks. The prairie, estuary, coast, river, and forest ecosystems contain a wide variety of animal and plant species. The ecosystems of RNSP preserve a number of rare animal species. Numerous ecosystems exist, with seacoast, river, prairie, and densely forested zones all within the park. The tidewater goby is a federally listed endangered species that live near the Pacific coastline. The bald eagle, which usually nests near a water source, is listed as a state of California endangered species. The Chinook salmon, northern spotted owl, and Steller's sea lion are a few of the other animal species that are threatened. Over 40 species of mammals have been documented, including the black bear, coyote, cougar, bobcat, beaver, river otter, black-tailed deer, and elk. Along the coastline, California sea lions, Steller sea lions and harbor seals live near the shore and on seastacks, rocky outcroppings forming small islands just off the coast. Dolphins and Pacific gray whales are occasionally seen offshore... Read More

Grand Teton is the tallest mountain in the Teton Range. The park's historic Jackson Hole and reflective piedmont lakes teem with endemic wildlife, with a backdrop of craggy mountains that rise abruptly from the sage-covered valley. Grand Teton National Park is an almost pristine ecosystem and the same species of flora and fauna that have existed since prehistoric times can still be found there. More than 1,000 species of vascular plants, dozens of species of mammals, 300 species of birds, more than a dozen fish species and a few species of reptiles and amphibians exist. Due to various changes in the ecosystem, some of them human-induced, efforts have been made to provide enhanced protection to some species of native fish and the increasingly threatened whitebark pine...

Yosemite features sheer granite cliffs, exceptionally tall waterfalls, and old-growth forests at a unique intersection of geology and hydrology. Half Dome and El Capitan rise from the park's centerpiece, the glacier-carved Yosemite Valley, and from its vertical walls drop Yosemite Falls, one of North America's tallest waterfalls at 2,425 feet (739 m) high. Three giant sequoia groves, along with a pristine wilderness in the heart of the Sierra Nevada, are home to a wide variety of rare plant and animal species... Read More
