Yorktown and its neighboring rural crossroads sit at the junction of Whiteside, Bureau, and Henry Counties in this mid-2010s topographic study. The landscape is defined by an extensive drainage network, including the Fairfield Ditch Number 1, Wildcat Ditch, and the Fairfield Union Special Ditch, which manage water across this fertile agricultural region. This infrastructure highlights the long-term engineering required to maintain the productivity of the Illinois prairie.
