Warrens, Monroe County. July, 1959. Altitude c. 5,000 feet. Several large cranberry bogs are highlighted by the white sand of dikes and roads. Some small lakes, extensive marshland, and a few areas of trees occupy the major portion of this verdant landscape, once beneath the waters of Glacial Lake Wisconsin. This is the state's primary cranberry-producing locality. Wisconsin and Massachusetts vie for the top position among the states in cranberry output.
