    Cranberry harvest

    Cranberry harvest — A Massachusetts cranberry bog holds a bounty of ripe red fruit. During the fall harvest, growers flood bogs, then mechanically churn the water to dislodge cranberries from their low-lying vines. They round up the floating fruit with booms, and convey it to receiving stations for cleaning. Photo by Steve Dunwell.
