...still, however, some places where the tallgrass prairie remains nearly as the pioneers saw it--vast, rolling expanses reaching beyond the horizon. U.S. environmentalists would like to keep it that way, and so would the National Park Service. Last month Park Service Director William Penn Mott toured the proposed site for the nation's first Tallgrass Prairie National Preserve: 50,000 acres near Pawhuska, in the Osage Hills of Oklahoma. "You have a jewel here," he told ranchers and conservationists at a barbecue on the Foraker Ranch, one of the properties that could make up the preserve, "and the jewel...
...bison and elk are virtually gone, and preserving what remains of the prairie has long been a challenge for conservationists. An effort to establish a tallgrass park at a site in Kansas foundered seven years ago because of local opposition. Ranchers were reluctant to surrender commercially exploitable land...
...total moratorium and have not detonated a nuclear device since August 1985. But some of the weapons envisioned by SDI require underground nuclear tests. The Pentagon argues that testing is needed to ensure the reliability of its arms stockpile. While continuing with tests, the U.S. has proposed that on-site monitors be permitted to verify the current ban on detonations with yields greater than 150 kilotons. When the U.S. suggested in March that both sides adopt a new, sophisticated verification system called CORRTEX, the Soviets rejected it. Two months later, however, the Soviets struck their agreement with the Natural Resources...
...network of stations that accurately monitor Soviet tests. Even so, the American observers should collect invaluable data on the seismological characteristics of the Soviet Union and on the Soviets' ability to read tremors from U.S. nuclear tests. The project's primary goal, said Archambeau, is to "demonstrate that on-site inspection is feasible and should be no obstacle to a test moratorium." Added M.I.T.'s Kosta Tsipis, an expert on verification: "Scientists are showing that on-scene inspection works. Now it's up to the politicians." Given the convoluted nature of arms control, the hard work lies ahead...
...other material may have sifted into the toe marks long after the prints hardened. Or perhaps, for some reason, erosion distorted the prints. Even before Kuban's findings, mainstream scientists did not lose much sleep over the Paluxy footprints. Says Harvard Paleontologist Stephen Jay Gould, who has visited the site: "Everyone knows that they are dinosaur tracks. It's been a non-issue in the field for a long time." The question of whether some dinosaurs stepped heel first, however, remains. Kuban's contention that they came down on their metatarsals "fundamentally reorganizes what we know about the foot anatomy...
