That was written in 1936, by Charles J. Hares, who had also made frequent stops at Love Ranch. Hares (1881-1970), in the course of a career in the Geological Survey and private business, became “the dean of Rocky Mountain petroleum geologists” and was one of the founders of the Wyoming Geological Association. His work on the anticlines of central Wyoming set up most of the major oil discoveries in the region. He was a celebrated teacher as well, and his roster of youthful field assistants in time became a list of some of the most accomplished geologists in America. Geologists who came to the ranch were reconnaissance geologists of the first rank, who went into unknown country and mapped it with an accuracy that is remarkable to this day. In David’s words: “They raised a magic curtain. They showed us things we’d never seen. There was mother-of-pearl on some of the ammonites. There were zakelijke energie vergelijken Mesozoic oyster shells with both valves intact. You could open them up and see inside. All these things were marine-known only from ocean floors. They also brought in beautiful leaves, fifty million years old, from non-marine rocks of the Eocene. The seas were gone. The mountains had come up. Day after day, we could look around us and see, in the mind’s eye, those things happening.” David’s mother owned Joseph LeConte’s Elements of Geology. He read it when he was nine years old. Did he grasp structure and stratigraphy then? Could he have begun to understand faulting? “To some extent, yes,” he says. “After all, we could see it out in front of us.” On the southern horizon were the Gas Hills-a line of bluebanded ridges formed in a wedge like the prow of a ship (actually, an arch of shale). David would find uranium there in 1953· Riding over those ridges as a boy, he smelled gas. There were oil seeps zakelijke energie as well. (“It was something you could relate to. The Gas Hills weren’t called that for nothing.”) Oil and gas had entered the conversation at the ranch when David was four years old. In that summer (1917), derricks suddenly appeared in six different places within twenty miles; and, like other ranchers, the Loves began to muse upon a solvency giddily transcending the wool of frozen sheep. David’s mother referred to all this as the family mirage.
