...scene, you can saunter along the lengthy peaks of the Sand Dunes near Stovepipe Wells, where desert winds have deposited grains of mountain quartz in a beach-like expanse that covers 15 sq. mi. Or you can visit Devil's Golf Course, where wind and rain have shaped the silt of ancient saltwater lakes into surreal crystallized salt pinnacles. And there's no place better to observe the tectonic forces that shaped Death Valley than at Badwater, the lowest place in the valley (and on the continent), where a salt-and-silt bog hundreds of feet below sea level rises...
...Chinese, who have been farming fish for 2,000 years, pioneered a method in which nothing is wasted. Farmers dig ponds around rice paddies and feed carp in the ponds with weeds from the rice field. The silt from the ponds is used as fertilizer for the fields, and crabs are grown to eat pests. Some of those techniques are being adapted in Western fish farms. In Tuscaloosa, Ala., Dan Butterfield, 59, raises bass, carp, catfish and other species in the same pond; the sun and the catfish feces stimulate the growth of phytoplankton, which feeds the other species...
Sixteen sailors died when the Monitor sank. Scientists found the human remains in the raised turret, along with a pocketknife, a leather boot and a coat button. They hope to find more artifacts when they clean out the tons of silt that remain in the turret...
...dams profoundly altered the character of the Missouri, evening out its pulse--the naturally occurring spring rises and summer drops--and capturing much of the silt that gave the waterway its nickname "Big Muddy." The dams offered protection to some 1.4 million acres of rich, river-hugging farmland, curtailed damaging floods and made it possible to hem in the shifting riverbanks with miles of concrete levees and retaining walls. And for the 10 million inhabitants now living and working along its 2,341-mile path, the multitasking Mo is a source of drinking water, electricity and irrigation and a resource...
...fiscal conservatives dislike the federal subsidy the barges receive. They say any savings will benefit the barge companies, not the farmers. And environmentalists are concerned that bigger locks will bring more barges, killing more fish with their propellers and filling more backwaters with silt. "It's amazing how clear the river water is in the winter when barge season is over," says Dan Specht, who grows 800 acres of soybeans in McGregor, Iowa, four miles from the river. "The muddy water hurts plants by putting silt on their leaves, and it hurts fish with silt on their eggs...
