NASA Adds To Evidence Of Mysterious Ancient Earthworks

High in the skies over Kazakhstan, space-age technology has revealed an ancient mystery on the ground. Satellite pictures of a remote steppe reveal colossal earthworks - geometric figures of squares, crosses, lines and rings the size of several football fields, recognizable only from the air and the oldest estimated at 8,000 years old.
Two weeks ago, in the biggest sign so far of official interest in investigating the sites, NASA released clear satellite photographs of some of the figures from about 430 miles up.
