Residents of Anchorage, Alaska, saw a dramatic demonstration of that strange phenomenon during the disastrous 1964 earthquake, says Columbia University Geologist Paul Kerr, whose investigation is described in the current issue of Scientific American. While probing beneath the battered sand, gravel and silt surface of Anchorage during the past two summers, Kerr studied an underlying layer of quick clay from 10 to 30 ft. thick. During the three minutes of the quake's violent up-and-down jolting, he concluded, some of the quick clay under Anchorage turned into liquid, triggering the damaging landslides that literally floated large sections...
Mother Lode. Geologist McNair made his discovery last summer after sighting a distinctive rock ledge on remote Victoria Island in the Canadian arctic. Clearly visible on the surface of the Pre-Cambrian rock, which had somehow escaped the disturbances of mountain building and the pressures of overlying rock, were the fossilized tracks of burrowing, wormlike animals -an encouraging indication that more fossils might be near by. Says McNair: "I knew how gold prospectors felt when they stumbled across the mother lode." Splitting open the rock, he found the remains of 47 primitive, clamlike brachi-opods that radioisotope dating proved...
Died. Arthur Holmes, 75, foremost British geologist, author of the classic textbook, Principles of Physical Geology, whose pioneering use of radioactivity as early as 1913 in determining the age of rocks paved the way for the geological time scale, which places the origins of the earth at 4.5 billion years; of uremic poisoning; in London...
Glaciers move only inches a year and, besides, on orders of the Swiss government, Geologist Auguste Lombard last year examined Allalin and reported that the great ice sheet was retracting, not expanding...

Those not killed outright must have frozen to death in a matter of hours." At a news conference in Geneva, Geologist Lombard said that the disaster had been "completely unpredictable...
