Lake Clark National Park and Preserve is a United States National Park in Port Alsworth, Alaska. It was first proclaimed a national monument in 1978, then established as a national park and preserve in 1980 by the Alaska National Interest Lands Conservation Act. The park includes many streams and lakes vital to the Bristol Bay salmonfishery, including its namesake Lake Clark. A wide variety of recreational activities may be pursued in the park and preserve year-round. Located about 100 miles (160 km) southwest of Anchorage, the park includes a variety of features not found together in any of the other Alaska Parks: the junction of three mountain ranges, a coastline with rainforests along the Cook Inlet, a plateau with alpine tundra on the west, glaciers, glacial lakes, major salmon-bearing rivers, and two volcanoes, Mount Redoubt and Mount Iliamna.
