6．Archaeologists searching for a lost city in the forests of Honduras have discovered the urban remains of what they believe is a vanished （消失的） ancient civilization．A writer and photographer for a magazine accompanied a team of scientist to Honduras'Mosquitia region reporting a legendary"White City"or"City of the Monkey God．"
The expedition was made after aerial light diction scanning（机载激光雷达检测）-known as LIDAR-uncovered what appeared to be man-made structures below the rainforest．Seeking to confirm the discovery，a team of U．S．and Honduran researchers entered the remote region．They were protected by Honduran Special Forces．
Writer Douglas Preston said the team emerged on February 25，after documenting the ruins of a"vanished culture．""In contrast to the nearby Maya，this vanished culture has hardly been studied and it remains virtually unknown．Archaeologists don't even have a name for it，"Douglas wrote．Archaeologists no longer believed in the existence of a single"While City，"he said，instead believing there had been an entire civilization with many cities．
The expedition found earth works，including an earthen pyramid as well as a collection of stone sculptures．Archaeologists from Honduras estimated they dated from A．D 1000to 1400．
The researchers were greeted by wildlife which appeared never before to have seen humans，wandering unafraid through their camp．This is clearly the most undisturbed rainforest in Central America．The team left their finds untouched and are keeping the exact location of the site secret in an attempt to prevent looting （洗劫）．
But Douglas warned that the area was nevertheless under threat，with illegal logging （砍伐） for cattle farming within a dozen miles．A local director said that the forest and valley could disappear within eight years unless action was taken．"The Honduran government is trying to protect this area，but doesn't have the money．We urgently need international support．"
