One of the most dramatic eras in Indiana history, the natural gas boom in the east central region transformed a mostly agricultural area into a major industrial center. The discovery of natural gas created major cities in the place of county seat towns, boomtowns where there had been villages, and factories towering over former farm land. The impact of the boom lived on even after gas itself failed. Through a collection of vintage images, authors James A. Glass and David G. Kohrman provide an overview of the boom era and its legacy in the four county seats of the gas belt: Muncie, Anderson, Kokomo, and Marion, as well as smaller communities such as Elwood, Fairmount, and Gas City.
