Walworth, for most of its history, has been principally a farming community. Much of the terrain is hilly, with ridges (called drumlins), running mostly north and south, which were formed thousands of years ago by huge glaciers. In the lowland areas between the hills were swamplands. It was these swamplands that attracted the Dutch immigrants as they migrated westward. They saw the potential of these swamplands and with their knowledge of hydrology gained from the experience in their homeland, drained the swamplands and, from them, formed muck land: rich black soil, which was excellent for raising such crops as potatoes, celery, lettuce, onions, carrots, beets, etc.
