Satellite data can help limit the dangers of windblown dust

Interstate 10, an artery that cuts through the rural drylands of southern New Mexico, is one of the country's deadliest roadways. On one stretch of the highway, just north of a dry lakebed called Lordsburg Playa, fatal collisions occur with such regularity that officials often call it the "dust trap." It's a fitting name. Since 1967, at least 55 deaths in the area have been linked to dust storms.
