与我们理解的那种湖光水色、亭台楼阁的公园不同,美国的公园或纪念公园是自然保护区,是引人入胜的地质博物馆或化石展览馆。位于怀俄明州的黄石公园是举世闻名的地质博物馆。这里有世界上最大的间歇喷泉群,其中的汽船喷泉自1962年以来每隔五天至十月喷发一次,水柱高达80—115米,巨人喷泉则测到过每小时3700多吨的涌水量。除其它各种地质现象外这里还生存有各种野生动物,化石则以尚保持直立状态的化石森林而著称。无独有偶,在亚利桑那州有一硅化木森林公园,
Unlike the lakes, aqua and pavilions we understand, parks and memorial parks in the United States are nature reserves and fascinating geology museums or fossil exhibition halls. Yellowstone, Wyoming, is a world-renowned geology museum. Here is the world’s largest group of intermittent geysers, including the Steamboat Fountain that erupts every five to October from 1962, with water columns of up to 80-115 meters and the Giant Fountain measuring over 3,700 tons of water per hour. Among various other geological phenomena there are all kinds of wild animals alive, while fossils are famous for their fossilized forests that remain upright. Coincidentally, there is a siliconized forest park in Arizona,
