Surface Man. Throughout his explorations, Glueck remained a "surface man," which means that he covered large areas, guided by reason, tradition and literary clues, and learned what he could from surface finds.

To the strict diggers, the edu cated estimates of the surface men are all too fallible. The balanced truth is that each method has advantages, de pending on the nature of the country and the sites...
...Australia itself. Like the U.S. Wild West, Australia's vast mid-continental frontier has been a breeder of legends. And always the theme is man against terrifying odds. It may be drought, heat or the devastating loneliness of an outback town; the protagonist may be a gold digger, convict, explorer or the legendary Aussie bandit, Ned Kelly, defying a continent...
...University of California, using a potassium-argon isotope dating system, were able to show that flat-browed Zinjanthropus lived some 1,750,000 years back in prehistory, the oldest manlike animal yet found. By measuring the amount of potassium 40 and its decay product, argon 40, in a digger's find, scientists conceivably can fix an object's age at 50 million years, with a probable error of less than 2%. The radioactive carbon dating system, for which Dr. Willard Libby won a Nobel Prize in 1960, reaches back for only 50,000 to 60,000 years...
