If you travel to Greensburg, Kansas, you can pay a visit to what is billed as the “World’s Largest Hand-Dug Well.” Construction on the well began in the 1880s. As the railroads made their way across Kansas, a reliable source of water for the steam engines was essential. The work was done by teams of men using hand tools—shovels, picks, half barrels, pulleys, and rope. As they made their way downward, they lined the well shaft with limestone rock. The finished well is more than one hundred feet deep and more than thirty feet in diameter.
