...Wildcatters drilled where they could find oil seeping from the ground. Now, drilling for oil is highly complicated and expensive, especially the way Amerada does it. Oilmen have suspected for years that there was oil in the Williston Basin. A saucerlike underground formation, the basin is composed of sedimentary strata which were once the bottom of a prehistoric sea-the type of formation in which oil is found...
They are using "varsity improved sampling methods and are taking pains to dig deeply into the lower economic strata of the population," he said. They are interviewing in the evening rather than the daytime so as to catch working men at home...
...greatest treasure hunt in U.S. history is in full cry. Above the green of North Dakota wheatfields rise the spidery towers of oil-drilling rigs. On the plains of Utah, shirt-sleeved crews set off dynamite blasts and, from the vibrations, map the subterranean oil-bearing strata. Over Alabama cottonfields fly planes with strange; antenna-like tails, which pick up magnetic waves and thus record geological formations below. In West Texas, wildcatters, trucks loaded with tools, inch across the prairies like gypsy caravans...
...Mountain Boys. Denver is the center of the eleven-state Rocky Mountain Region, which was flooded by prehistoric seas that once covered most of the U.S. and laid down the oil-bearing strata along its shore and on its bottom. One Denver geologist talks sweepingly of "a great underground river of oil flowing from Northern Alberta to the Rio Grande." More than $130 million was spent in the area last year tapping the "river." Refineries are being expanded and new ones built; new pipelines are fanning across the mountains...
...Sloping Strata. Though the new route appears more hazardous in many ways than the old, it has certain advantages. The climbers will not have to cope with the full force of the prevailing northwesterly gales; the rock strata dip down from south to north, making the south side more suitable for camp sites, and eliminating overhangs; and most important, the climber's morale, which ebbs dramatically at the 27,000-ft. level, will be aided by the full force of the sun's rays, which are quickly blanketed on the north face...
