风洞国家公园，美国南达科他州

风洞国家公园建立于100年前，位于著名的黄石国家公园和恶地国家公园之间，这里生活着北美仅有的四大纯种野牛之一。20世纪初，动保人士从屠刀下救了20头野牛。今天照片里的两头野牛就是这20头野牛的后代。那时，野牛仅存不到1000头，而野牛的数量曾一度达到5000万头。在地上，这里有美国最大的草原；在地下，这里有世界上最大的洞穴体系之一。随着天气的变化，空气在洞穴进出，风洞国家公园也因此得名。

Wind Cave National Park, South Dakota, USA

Between the more famous national parks of Yellowstone and the Badlands lies Wind Cave. Established 100 years ago, this national park is home to one of only four wild herds of genetically pure bison in North America. These two are the descendants of 20 bison saved from slaughter by conservationists in the early 1900s. At the time, fewer than 1,000 wild bison were left alive out of a population that once numbered 50 million. Above ground, the park is the largest grass prairie in the country. Below ground lies one of the most extensive cave systems in the world. As the weather above changes, air flows into and out of the caves creating the wind for which the park was named.
