...March, and the smoking has not stopped since. One of a dozen major volcanoes in the western U.S., the 10,778-ft. Mount Baker is now venting several thousand pounds of sulfurous gases and debris every hour. Right below the mountain's summit, the 1,600-ft.-wide crater is so thick with fumes that geologists can enter only with gas masks. Does this spectacular activity foreshadow the first major eruption in the lower U.S. in a half-century? U.S. Geological Survey scientists refuse to speculate. "Some volcanoes erupt with hardly any warning," explains Geologist Mark F. Meier. "Others...
...total of only twelve tickets. To Winner Cline, the worst hazards after rain and a sandstorm were unwary rabbits. "I got one at 130 m.p.h., and another at 140 m.p.h., but it was the one at San Bernardino that did us in," he said, pointing to a cottontail crater on the Ferrari's fender...
...simultaneous detonation of a row of three 15-kiloton nuclear charges (compared with 20 kilotons for the Hiroshima bomb), spaced about 500 ft. apart. The blasts produced so little radiation and such stable walls that technicians were able to walk along the rim of the 2,600-ft.-long crater only two days later. The only damages were some cracks in the brick ovens and wall plaster of nearby log cabins. Although the Russians have not done any further blasting, they say that the job could be done with some 250 nuclear devices, mostly in the 100- to 200-kiloton...
...like the moon and it isn't," said Donald E. Gault, one of the scientists monitoring the Mariner data at NASA'S Jet Propulsion Lab in Pasadena, Calif. The pictures showed that Mercury's craters are much flatter and thinner-rimmed than the moon's and resemble giant pie pans-an indication that they may have been worn down by some yet-to-be-identified erosional process. Like most of their lunar counterparts, Mercury's craters were apparently created by impacts of asteroid-size chunks of material rather than by volcanic eruptions. Indeed, one crater...
...some point halfway up the slope of the La Paz canyon, rural and urban Bolivia meet. The Indian Quarter of the city is situated just where the western wall of the crater begins to rise sharply. The narrow sidestreets here are lined with the old, deteriorating shops and grocery stores owned by the mestizos (people of mixed white and Indian blood). Most of the real activity, however, takes place not in these dusty little buildings, but in the streets themselves. Everyday the Indian peasants, who live higher up in the poorer sections of the city, make the long, strenuous climb...
