Lake Clark is home to diverse wildlife, including all five species of Pacific salmon, which support both brown and black bears. The park hosts one of the world's largest concentrations of brown bears, particularly during salmon runs. Other notable mammals include moose, caribou, Dall sheep, wolves, and wolverines. The park's waters support harbor seals, beluga whales, and various fish species. Bird life is abundant, with bald eagles, trumpeter swans, and numerous waterfowl species. The region serves as an important migration corridor for many bird species.
The park's vegetation varies dramatically with elevation and proximity to the coast. Coastal areas feature lush rainforests with Sitka spruce and western hemlock, while interior regions support boreal forests of white spruce, birch, and poplar. Alpine tundra above treeline displays colorful wildflowers during brief summer blooms, including lupine, fireweed, and alpine azalea. The park's wetlands host numerous sedges, rushes, and aquatic plants. Wild berries, including blueberries, cranberries, and crowberries, are abundant in season and are important food sources for wildlife and subsistence users.
The park showcases dramatic geological features shaped by volcanic and glacial activity. Two active volcanoes, Mount Redoubt and Mount Iliamna, dominate the landscape and are part of the Pacific Ring of Fire. The region has been sculpted by multiple glacial periods, creating deep U-shaped valleys, numerous lakes, and rugged coastlines. The park sits at the intersection of three mountain ranges: the Alaska Range, Aleutian Range, and Chigmit Mountains. Tectonic activity continues to shape the landscape, with frequent small earthquakes and occasional volcanic eruptions.
The area now known as Lake Clark National Park has been home to Dena'ina Athabascan people for thousands of years, who maintain a subsistence lifestyle in the region. Russian explorers first arrived in the late 1700s, followed by American prospectors during the gold rush era of the late 1800s. The park was established in 1980 under the Alaska National Interest Lands Conservation Act, protecting 4 million acres of pristine wilderness. Richard Proenneke, whose hand-built cabin still stands in the park, lived here for 30 years and documented his experience, bringing national attention to the area's natural beauty.
Lake Clark itself is a stunning 42-mile-long turquoise lake surrounded by mountains, serving as the park's centerpiece. Proenneke's Cabin, a National Historic Site, demonstrates wilderness living and craftsmanship. Twin Lakes offers spectacular mountain views and excellent fishing opportunities. The park's coastline along Cook Inlet provides habitat for marine life and opportunities to view both brown bears and volcanoes. Tanalian Falls and Kontrashibuna Lake are popular destinations for day hikers. The park's numerous glaciers, including the Tanaina Glacier, offer opportunities for ice climbing and glacier viewing.
Lake Clark National Park experiences a transitional climate between maritime and continental zones. Summers are relatively mild with temperatures ranging from 50°F to 70°F (10-21°C), while winters are cold, averaging 0°F to 30°F (-18 to -1°C). The park receives significant precipitation, with coastal areas getting up to 200 inches of rain annually. Weather can change rapidly, and visitors should be prepared for rain, wind, and sudden temperature shifts even in summer. Snow typically covers the ground from November through May, with higher elevations maintaining snow cover year-round.
