Product Description
IN THE EARLY YEARS OF THE twentieth century, an enormous bowl-shaped hole in the high plains of northern Arizona was investigated by a mining engineer and his associates. The hole was almost three quarters of a mile wide-a little over one kilometer¹-and it penetrated thick layers of subsurface rock. The investigators concluded that it was created thousands of years ago when a mass of meteoritic iron struck the earth, and they produced extensive evidence in support of their claim.
From the Inside Flap
The scientific community has argued for decades over the origin of giant craters on the earth. In a highly readable fashion, Kathleen Mark recounts the fascinating detective story of how scientists came to recognize metorite craters, both ancient and relatively recent.
