RADAR PENETRATES PUEBLO SECRETS

摘要

Five circular depressions in the desert north of Bluff, Utah, have long been a source of tantalizing frustration to archaeologists. For the past two decades, the prevailing theory was that the desert hollows conceal five great kivas—subterranean circular masonry structures approximately 40 feet in diameter where ancient Pueblo people gathered more than 700 years ago to perform religious rituals. Although researchers have longed to excavate the site, called Comb Wash, the cost—roughly $1 million—and the time—about five years—have been prohibitive, not to mention the opposition by Native Americans to disturbing sacred grounds.
