冬天的布莱斯峡谷石林 Bryce Canyon hoodoos in winter

布莱斯峡谷国家公园

当太阳在布莱斯峡谷升起时，白雪皑皑的橙红色岩石闪闪发光。这些修长高耸的岩石被称为石林，而布莱斯峡谷国家公园正是因为拥有地球上密度最高的石林而闻名。这些石林的下层是松软的沉积岩，上面则覆盖着一层更为坚硬的石盖。犹他州冬天的冰霜会侵蚀石盖，最终暴露出底下更易被侵蚀的岩石。值得庆幸的是，这些石林现在还屹立不倒，让我们可以在公园成立100周年之时欣赏大自然的鬼斧神工。

Bryce Canyon National Park turns 100

As the sun rises on Bryce Canyon, its snowcapped red-orange rock formations start to glow. These slender, towering rocks are called hoodoos, and Bryce Canyon National Park is remarkable for having the highest concentration of hoodoos anywhere on Earth. The hoodoos here have a soft base of sedimentary rock with a cap of more solid stone on top. The snow and frost of the Utah winter will eventually erode the support of the cap, causing it to fall and expose the remaining rock to easier erosion. Thankfully these formations are standing now, allowing us to take in their natural majesty as the park celebrates its 100th anniversary.
