猶他州的布萊斯峽谷國家公園
hoodoo是什麼？您曾將它與岩石聯想在一起嗎？
猶他州布萊斯峽谷國家公園內，大部分的美景及特色都是肇因於侵蝕作用，即地層表面受外力磨損，如水力或風力。Hoodoo是形狀奇特的石柱，外觀時常狀似小妖精或其他的超自然角色。事實上，曾住在此區的派尤特族印地安人，將它們叫做「傳奇人物」。
雖然它們可能長得像人，但這些岩石卻是由大自然形成的。水的物理及化學作用會侵蝕龐沙岡特高原的遠古岩石，它會帶著砂礫、碎石穿越石頭的表面，趁機滲入表面的隙縫，再分解它。不同的岩層擁有不同的硬度，因而侵蝕作用所造成的磨損情況也各不相同，所以就會形成奇異而獨特的形狀。除了hoodoo之外，其他的形狀還包括了蠩狀、螺旋形及尖塔樣。
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.
