Lake Clark's first people are of Alaska Native descent and came to this region a millennia ago. In more recent times, Russian explorers and missionaries arrived in the 18th century, quickly followed by prospectors, trappers, and entrepreneurs from Western Europe, Canada and the United States. Despite this relatively rapid exposure to the wider world, the native communities of the region retain their traditions and languages. Today's Lake Clark is a mix of various ethnicities, founded upon a collaborative history.
Lake Clark National Park and Preserve is a place where natural processes dominate. Four of the five biotic communities found in Alaska - coastal, lakes/rivers/wetlands, tundra, and boreal forest - exist in the park. Two active volcanoes - Mount Iliamna and Mount Redoubt - tower above the landscape. Glaciers wind their way down into valleys where the Alaska and Aleutian ranges join.
Flora and fauna
A full complement of subarctic fish, wildlife,and plant species make their homes in Lake Clark National Park and Preserve's various ecosystems. Salmon pass through tidal estuaries on their way to spawning grounds in mountain lakes and streams, chased by hungry seals and brown bears. Dall sheep share treacherous mountain slopes with delicate alpine wildflowers. Once-endangered peregrine falcons occupy eyries on cliffs where they can easily hunt migrating and nesting waterfowl. Follow the links below to explore the plants and animals of the park and preserve.
Lake Clark has two distinct climate areas: the coast and the interior. The coast is wetter and experiences milder temperatures. The interior gets half to one fourth as much precipitation, but temperatures are hotter in summer and colder in winter. Frost and snow can occur any time parkwide, but are most common from September to early June. Lakes here typically begins freezing in November and melting in April. Ice conditions dictate whether planes need floats or skis to land on lakes.
Almost all visitors must arrive by air. The park's lands and waters are open to fixed-wing aircraft. There are no fixed runways or FBO services within the park. Port Alsworth, immediately west of the park, has two private airstrips (ramp fee will be charged) where fuel is available.
Weather and tides permitting, the coastline may be approached by boat.
There is no car access to any part of the park.
