Lake Clark National Park and Preserve is a place where natural processes dominate. Salmon pass through tidal estuaries on their way to spawning grounds in mountain lakes, chased by hungry seals and brown bears. Two active volcanoes - Mt. Iliamna and Mt. Redoubt - tower above the landscape. Glaciers wind their way down into valleys where the Alaska and Aleutian ranges join. Dall sheep share treacherous mountain slopes with delicate alpine wildflowers. Continuously inhabited since early prehistoric times, the Lake Clark region nevertheless remains sparsely populated by humans. Follow the links on the left to explore the ecology and wildlife of the park and preserve.


Geology, biology, botany, volcanology, paleontology - the list of subjects for scientific study in the park and preserve is nearly endless. National Park Service with United States Geological Survey scientists conduct long-term monitoring projects on vital plant and wildlife indicators designed to monitor the health of the park's ecosystems. University researchers often conduct research in the park and the National Park Service is eager to work with independent researchers working on projects which may help inform park management.Visit our research section for more information.

Lake Clark National Park & Preserve is part of the territory of the Mulchatna caribou herd.

Caribou often travel high into the mountains in the summer to rest on patches of remaining snow and ice, where they can escape clouds of biting insects.
