大自然慢慢来(Nature took its time.)

这个地方不是一夜之间建立的；大自然花了3亿多年的时间形成了这个奇迹。美国犹他州的洛斯阿科斯国家公园展示了2000多个自然拱门，这些拱门是在古代海洋留下盐层时形成的，入口和纳瓦霍砂岩层慢慢破裂和磨损。

This place was not created overnight. It took nature more than 300 million years to form this wonder. Arches National Park, Utah, shows more than 2,000 natural arches that formed when ancient seas left salt beds, and Entrada and Navajo sandstone layers slowly cracked and wore.
