Twenty miles southeast of Salt Lake City, the buff granite cliffs surrounding Little Cottonwood Canyon are broken by barred, concrete-framed tunnel openings. Behind the bank-vault doors with in, protected by a temperature that remains almost constant near 57 °F., and a humidity that hovers between 40% and 50%, is the world's largest collection of family records: more than 650,000 rolls of microfilm carrying more than 500 million pages of genealogical statistics going back as far as the 14th century. Only the direct hit of a nuclear bomb could endanger them...
...months, proud Mexicans have been lining up on Sunday afternoons by the thousands to gawk at the project and its artfully decorated stations, including one built around an Aztec pyramid unearthed during the excavations. They have dubbed the subway "el Cajon" (the Box), from the shape of the concrete tunnel that en cases...
That shape, and the ingenious engineering that made the project feasible, is the handiwork of Mexico's largest builder, Bernardo Quintana. His box tunnel literally floats like a ship on subsoil that is 80% water. The trick was to remove precisely the right weight of soil and water without undermining buildings alongside the right of way. To do so, Quintana first built sidewalls for a trench, then removed the muck between them through a complex electroosmosis process of his own devising. The roof to form a tunnel came last. By the time the whole subway is completed in November...

All sorts of tunnel-vision agencies, from the Agriculture Department to the Army Corps of Engineers, have pursued narrow goals that destroy delicate balances in nature and sometimes endanger human life. The glaring need is an overall body to coordinate the goals and protect the environment in a systematic...
...Manned Spacecraft Center, the van will be rolled up to the Lunar Receiving Lab (LRL), an 83,000-sq.-ft., $15.8 million building designed specifically to house the astronauts and lunar samples during the quarantine period. After walking through an airtight plastic tunnel extended from the van, the Apollo crewmen and their two traveling companions will enter the astronaut-reception area, which occupies about a third of the laboratory. A dozen others -NASA physicians, technicians, a cook and a public relations man-will join them until the quarantine period ends...
