...mass three times greater than that of Grand Coulee Dam, could break loose, slide into the lake and trigger flooding. In September, researchers from Eastern Washington State College, wearing oxygen masks to protect them from the sulfurous fumes, made their way through cave passages in a 140-ft.-thick layer of ice and snow to reach the center of the crater. There they found a football-field-sized lake of steaming acid, some of which is leaking into streams fed by the mountain's melting snow...
Said, who heads the Geological Survey of Egypt and holds a seat in the Egyptian Parliament, bases his theory on evidence he found while doing test borings for the Aswan High Dam in 1961. In some of his core samples, Said was puzzled to find a layer of alluvial (deposited by running water) sediment at a depth of 450 ft., well below the level of the modern Mediterranean Sea. Convinced that such deposits could not have been left by today's Nile, Said began looking into the possibility that they were traces of an earlier river...
...more, possibly as a result of earthquakes, water from the Atlantic poured into the Mediterranean, flooding as far into Egypt as Aswan and covering the entire Nile Valley. For 2 million years the valley was a gulf of the Mediterranean. When the encroaching sea retreated, it left behind a layer of salt deposits and marine fossils for Said and fellow geologists to find...
Nail Bank. Like an artist preparing a canvas, the manicurist usually starts by strengthening and lengthening the nail with a special cement. The painting is applied on top of a layer or two of lacquer and is then covered with at least five protective coatings. The artwork will stay in prime condition for two or three weeks. Atlanta Manicurist Jean Dean tips clients' fingers with human nails that have been specially grown and sold to a "nail bank." Though most fashion plates keep their art at their fingertips, manicurists have a sizable toe trade among women headed for tropical...

The New York Times noted that April, with its whippoorwills, arrived on schedule soon after the departure of March and its curlews and gusty winds. On some fronts, though, we were losing fast. The ozone layer was dissolving and the polar ice caps melting. On the other hand, Venice stopped sinking...
