A big anniversary in the biggest state
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.
