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.

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...

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...
