Even the less active will find the parks fascinating, and why not? Viewing the strata exposed by the river in the Grand Canyon, the wind-weathered landscape of Bryce Canyon or the waterworn stalactites of Carlsbad Caverns is like looking backward through time. To watch an alligator glide through the Everglades is to see a world still unsullied by technology. Seeing a black bear beg for food beside a highway in the Great Smoky Mountains National Park (the most popular in the system, with 11.4 million visitors last year) is proof that even in this age of the atom...
...billion bbl., almost a 30-year supply at current consumption rates-but despite the name they are scarcely "proven" in the sense that a proposition in Euclidean geometry is; they are really only estimates based on the best available evidence. To determine proven reserves, geologists study earth strata by drilling for rock and fluid samplings. Often calculations predict probable output by comparing it with production from similar fields already in operation. Trouble is, real output seldom matches the estimates...
Possible reserves are more problematic. They represent, as one oil geologist puts it, "guesstimates," based largely on the observation of strata formations that in other areas have proved to encase oil and gas basins. The calculations can be miles off-literally, Alaskan topography intrigued oil geologists, but some thought that the reserves would be found on Alaska's south shore. Instead, the oil is gushing from the North Slope...
...South American dictators compounded into one, shuffles with his flat feet "like a senile elephant" through his declining years, remembering all that he has sown and reaped, left untouched or blighted. We watch his powers slowly rot over seemingly endless time, and plow with him through strata of recalled events...
