A huge escarpment called the Chinese Wall ripples across the landscape of the Bob Marshall Wilderness Area in Montana. In a 1985 National Geographic article, senior writer Mike Edwards said: "It does not look like China's wall, except that it crowns all and is gray rock, mostly limestone. To my eye it is a juggernaut of a tidal wave, surging out of the west, lifting its crest a thousand feet."
