About Wrangell-St. Elias
Wrangell-St. Elias is America's largest national park, containing four major mountain ranges and numerous glaciers and volcanoes. The park includes 9 of the 16 highest peaks in the United States. This vast wilderness area features diverse ecosystems from coastal to alpine, and preserves significant cultural sites from Alaska's copper mining era.
Fauna
Wrangell-St. Elias hosts diverse wildlife adapted to its extreme environments. Large mammals include Dall sheep, mountain goats, caribou, moose, brown and black bears, and wolves. The park's rivers support all five species of Pacific salmon, while its skies are home to numerous bird species, including golden eagles and trumpeter swans. Mountain valleys provide crucial habitat for smaller mammals like wolverines, lynx, and Arctic ground squirrels. Marine mammals such as sea lions and harbor seals can be observed along the park's coastal areas.
Flora
The park's vegetation varies dramatically with elevation and climate zones, creating distinct ecological communities. Lower elevations feature boreal forests dominated by white and black spruce, while coastal areas support lush temperate rainforests. Alpine tundra thrives above the treeline, displaying colorful wildflowers during brief summer blooms. The park's plant life has adapted to extreme conditions, with species like dwarf birch and various lichens surviving in harsh alpine environments. Unique microhabitats created by glacial valleys and thermal areas support specialized plant communities.
Geology
The park showcases an extraordinary convergence of mountain ranges, including the Wrangell, Saint Elias, and Chugach ranges, featuring 9 of the 16 highest peaks in the United States. Formed by ongoing tectonic activity, these mountains continue to rise as the Pacific Plate collides with the North American Plate. The park contains numerous glaciers, including the Malaspina Glacier, which alone covers over 850 square miles. Volcanic activity has shaped much of the landscape, with Mount Wrangell remaining an active volcano among several dormant ones within the park.
History
The park region has been home to Native Alaskan peoples, including the Ahtna and Tlingit, for thousands of years. Russian explorers arrived in the late 1700s, followed by American prospectors during the gold rush era of the late 1800s. The area's mining history is preserved in the historic Kennecott Mines, which operated from 1911 to 1938, producing some of the world's purest copper. Wrangell-St. Elias was designated as a National Park and Preserve in 1980 under the Alaska National Interest Lands Conservation Act, becoming the largest national park in the United States.
Notable Features
The park's most remarkable features include the historic Kennecott Mines National Historic Landmark, a remarkably preserved copper mining complex. Mount St. Elias, rising 18,008 feet, stands as the second-highest peak in both the United States and Canada. The Nabesna Glacier, one of the longest valley glaciers in North America, and the massive Malaspina Glacier system showcase the park's impressive ice fields. The McCarthy Road and Root Glacier offer unique opportunities for visitors to experience the park's rugged wilderness and geological wonders firsthand.
Climate & Weather
Wrangell-St. Elias experiences dramatic seasonal variations typical of Alaska's interior. Summers are relatively mild with temperatures ranging from 50-80°F (10-27°C), while winters are harsh with temperatures often dropping below -40°F (-40°C). The park receives moderate precipitation, with coastal areas seeing more rainfall than interior regions. Weather conditions can change rapidly due to the park's vast size and elevation changes, making it essential for visitors to be prepared for sudden shifts in temperature and precipitation regardless of season.
