cover ON THE COVER
Main photo: From the slopes Illopango Caldera looking north-northwest, Volcán San Salvador looms over the city of San Salvador, population 1.6 million. The main vent (Boqueron) is the rounded volcano in the middle of the skyline. The more conical-shaped peak to the right-middle of the skyline is El Picacho, a remnant of an older volcano. Photo by James Vallance, U.S. Geological Survey. See related stories on pages 14 and 18. Right top: At the Fossil Trace Golf Course near Denver, Colo., paleontologists discovered several well-preserved mammal tracks from the age of the dinosaurs.
