Geological Survey of the Territories) 。在这个科学调查团里，他们所负责的工作就是把怀俄明西北部与蒙大拿东南部，沿着黄石河一带地区绘制成并拍摄成图像。摩兰作了详细的纪录，他不但将这些区域的美丽常青的山峰与瀑布绘制成图画，他也画了很多比这张更奇怪的精细描绘的风景画。
Can a painting have an impact on society? Thomas Moran's paintings of Western landscapes inspired Americans to save their wilderness areas as national parks. Moran was born in 1837 on February 12. In the summer of 1871, Moran and photographer William Henry Jackson joined the U.S. Geological Survey of the Territories. Their job on this scientific expedition was to sketch and photograph lands along the Yellowstone River in northwestern Wyoming and southeastern Montana. Moran took detailed notes and made numerous sketches of the beautiful evergreen mountain peaks and waterfalls, but he also drew pictures of some sights even stranger than the one depicted in this painting.
