Every year, the plow turns up more stones in Ken Leach’s cornfield. It appears they’ve floated up through the rich Mettawee Valley soil from below the surface when in fact they’ve floated down upon the face of the earth from far above. There were once great clouds of ice between earth and sky. Ken’s stones were tucked into mile-high blankets of frozen water vapor. They’d been plucked from the even taller mountains that used to reign here, and carried in alluvial fans out across glaciers that were thousands of years in the making and thousands of years in the melting. When the land that is now a Vermont Land Trust protected property said goodbye to its last glacier, twelve thousand years ago, all the sediment and rock that was riding its coattails settled to the ground, creating the dark soil that farmers like for growing corn, plus, an unwelcome bounty of stones.
