DILLON, Lyman. (NY, June 12, 1800--Dec. 8, 1857). Settler. Dillon, a Cascade area farmer and sawmill operator, was hired in 1839 to establish a trail between Dubuque and Iowa City. The route, broken by a team of oxen pulling a great breaking plow, was a plowed furrow as straight as the animals and contour of the land would allow. This became the basis of a road planned by Congress from Dubuque to the Missouri border.
There remains a controversy whether Dillon was hired by R. C. Tilghman, the surveyor of the route, or James or Lucius Hart LANGWORTHY. Ironically the man who plowed this important pathway is not mentioned on the marker located south of Key West along the MILITARY ROAD.
