Preserving Alaska's natural beauty. Alaska National Interest Lands Conservation Act marks 42 years
On this day in 1980, the single largest expansion of protected lands in history doubled the size of the US National Park System. As a result, Alaska now has eight national parks, plus numerous monuments and preserves that protect more than 157 million total acres. When President Jimmy Carter signed the Alaska National Interest Lands Conservation Act, the public was granted the right to appreciate stunning locations like the one in today's photo: the braided river delta of the 51-mile-long Tlikakila River in Lake Clark National Park.
In the native Athabaskan language, Tlikakila literally means 'salmon are there river.' The park is known for its salmon-laden waterways and the fish are of major importance to the local economy and ecosystem. Local bear populations benefit from the excess salmon, and bear watching is very popular at Lake Clark. The abundance of salmon has also benefited a wolf pack within the park—the only one in the world known to be solely dependent on salmon.
