Explanation:
This starry night sky sparkles above the Black Hills of South Dakota and the United States' Mount Rushmore National Park. The historic site features enormous sculptures of four US presidents; George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln, carved into the southeast face of granite cliffs. Above the monumental symbols of the country's independence and early history, the night features stars and constellations familiar to northern skygazers around the world. Most noticeable are the stars of Ursa Major and the asterism known as the Big Dipper, almost resting upright along the cliff edge near picture center. Follow the arc of the Big Dipper's handle to get to Arcturus, the bright yellowish star in the lower left corner. Of course, a line extending through the dipper's two right most stars points to the upper right toward Polaris, planet Earth's North Star. Mount Rushmore一开始当然不叫做总统山，不过现在翻译为这个名字的也多了，原因大家看图就明白了。图最大就这么大了，所以本层直接上翻译。

美國拉希摩山的星夜
影像版權與提供: Wally Pacholka (TWAN)
說明:
這幅星夜出現在美國．南達科塔州拉希麼山國家公園的上空。此座山峰，因其東南面花崗岩懸崖雕塑有四位美國總統 (華盛頓、傑佛森、羅斯福和林肯)的巨大頭像而著稱。在這座美國獨立和早期歷史記念碑上方的星空，是北半球世界各地觀星人很熟悉星星和星座。其中最突出的是大熊座的眾星，以及位在影像中央懸崖上方名為北斗七星的星群。順著斗柄的曲向往左看，可見到影像左下角黃白色的大角星 (Arcturus)；而從斗杓右端的二顆星向右上沿伸，就可找到現在地球的北極星 (Polaris)。Mount Rushmore National Park (拉希摩國家公園)。
太帅了 别有风情啊 话说这样可以知道总统山的大致方位了~
