犹他州的布莱斯峡谷国家公园
hoodoo是什么？您曾将它与岩石联想在一起吗？
犹他州布莱斯峡谷国家公园内，大部分的美景及特色都是肇因于侵蚀作用，即地层表面受外力磨损，如水力或风力。Hoodoo是形状奇特的石柱，外观时常状似小妖精或其他的超自然角色。事实上，曾住在此区的派尤特族印地安人，将它们叫做「传奇人物」。
虽然它们可能长得像人，但这些岩石却是由大自然形成的。水的物理及化学作用会侵蚀庞沙冈特高原的远古岩石，它会带着砂砾、碎石穿越石头的表面，趁机渗入表面的隙缝，再分解它。不同的岩层拥有不同的硬度，因而侵蚀作用所造成的磨损情况也各不相同，所以就会形成奇异而独特的形状。除了hoodoo之外，其他的形状还包括了鯺状、螺旋形及尖塔样。
What's a hoodoo? Would you ever guess it has something to do with rocks?
Utah's Bryce Canyon National Park owes much of its beauty and character to the process of erosion -- the wearing away of a surface by forces like water or wind. Hoodoos are strangely shaped pillars that often resemble goblins or other supernatural characters. In fact, the Paiute Indians, who lived in this region, called them "Legend People."
Although they may resemble people, these rocks were formed by nature. Water has physically and chemically broken down the ancient rock of the Paunsaugunt Plateau by dragging bits of gravel and debris across its surfaces and by entering small holes in the rock and dissolving it. Various layers of rock differ in strength, so erosion does not wear away at them all at the same rate. Therefore, odd and irregular shapes have been formed. In addition to hoodoos, other shapes include fins, spires, and pinnacles.
