This is the story of a labor conflict in a mid-western industrial town, but I do not know if it describes any particular location or situation. A friend of mine who visits Pittsburgh, Pennsylvania often says Pittsburg obviously fits the description. A steel mill in a city built next to a river at the foot of (and partly on the slopes of) mountains. There are steep inclines around Pittsburgh that would fit Wright's description of a mansion and the Seer's house on top of a hill overlooking the city. Obviously this would not fit Gary, Indiana or Chicago, both of which are flat. Of course, the book does not actually say it was a steel mill, and I know of no evidence that Wright ever visited Pittsburgh, but my friend's guess does point out some of the characteristics of the city Wright describes in this book.
