アメリカ内務省さんのインスタグラム写真 - (アメリカ内務省Instagram)「Happy Summer Solstice! The official start of #summer, today is the longest day of the year. Denali National Park and Preserve in #Alaska is so far north that the park will get over 20 hours of sunlight today and only a few hours of twilight. If we were there, we'd spend that extra daylight exploring this amazing landscape of mountains, forests and tundra while keeping our eyes open for fascinating wildlife.
