The El Dorado Missouri-Pacific Depot began as a wooden structure in 1883 in a town of less than 2,000 people. It served as a center of activity and development for the community with news being brought in by train and other news transferred by the telegraph located at the depot.
El Dorado became, for a while, the world's storybook oil field. Butler County encompassed 1,800 producing oil wells on 25,000 acres. The El Dorado Field is a story of men and events that helped Kansas and the nation emerge from the draft-horse and kerosene-lamp years into the gasoline age. "
