Feature piece on the rock salt used on Maine's roads every winter. Each year, half a million tons of rock salt are shipped to Maine from mines in central Chile's Atacama Desert where salt flats cover more than a thousand square miles. Morton Salt is one of the state's primary suppliers. Ships carrying the salt arrive year-round at the Sprague Energy shipping terminal in Portland where longshoremen work 12-hour shifts to get the salt transferred to trucks.

The state has adopted some tactics for limiting the environmental impact.
