Denali National Park

Someone ought to tell these Dall sheep they don't blend in here at Polychrome Pass. Their white coats may be great camouflage against the Alaskan snows, but the warm tones of this tundra make them stick out a bit. And they aren't the only thing sticking out in this national park: It's home to the tallest mountain in North America.

Denali National Park and Preserve encompasses not only its namesake peak but more than 6 million acres of parkland like Polychrome Pass. And even this massive park is part of something bigger: The federal Alaska National Interest Lands Conservation Act, established on December 2, 1980, protected almost a quarter-million square miles of wilderness all over Alaska. As of today, 65% of the state consists of public lands.

德纳利国家公园

应该有人告诉这些达尔羊，他们不在多色山口混在这里。他们的白色外套可能是抵御阿拉斯加大雪的绝佳伪装，但这片冻土带温暖的色调让他们显得有些突出。它们不是这个国家公园里唯一突出的东西：它是北美最高山峰的所在地。

德纳利国家公园和保护区不仅包括其同名的山峰，还包括超过600万英亩的公园，如多色山口。甚至这个巨大的公园也是更大的东西的一部分：1980年12月2日制定的《联邦阿拉斯加国家利益土地保护法》保护了阿拉斯加全境近25万平方英里的荒野。截至今天，该州65%的土地为公共土地。
