While one diver, armed with a hammer and chisel, began chipping away around a copper ingot, trying to loosen it from concreted sediment, another culled the bottom, scooping sand with one hand and drawing it into a suction tube held in the other. Suddenly, something metallic flashed in the dim light filtering through the water. It was a piece of gold jewelry that had remained hidden from sight for 34 centuries. In the next several minutes, the team members uncovered more jewelry, a quartz bead, broken arrowheads and pottery shards, which they stored in a red-and-white plastic container...

...like neon and xenon, in the layer of Cretaceous clay deposited during roughly the same period that the dinosaurs became extinct. They were seeking to identify the nature of the object responsible for the impact. Because noble gases collect in carbon particles, the scientists isolated the carbon in Cretaceous sediment taken from Denmark, Spain and New Zealand. To their surprise, all three samples contained carbon that had been deposited at a rate 10,000 times as great as carbon in the layers immediately above and below them. It was bunched together in the fluffy patterns characteristic of common soot. Says...
...Earlier this year chemicals were found to be oozing into adjacent wetlands and into the Cochato--and leaching Lord knows where else, say the minority of townspeople who are upset. A water main that runs right under the site still supplies a thousand homes. Last spring the Cochato's sediment was found to include arsenic and naphthalene. Then last summer even the EPA seemed jolted: high concentrations of dioxin were discovered at Baird & McGuire...
...away. That is because the shoreline is made of solid rock and thus shakes less violently. Mexico's capital, however, was built on an alluvial lake bed. As a result, the seismic waves, though diminished in intensity on their trip from the coast, were amplified in the city's sediment foundation. Many tall buildings in the densely populated metropolis may not have been built to rigid quake- resistant standards. Indeed, some turned out to be just the right height to vibrate or resonate sympathetically with the frequency of the seismic waves, thus shaking with greater vigor than other buildings...
