Greenville, Mississippi in The Mansion (Location)

In a passage about a possible government airfield in Yoknapatawpha, Faulkner locates the county in between "the flatter prairie land to the east near Columbus" and "the perfectly flat Delta land to the west near Greenville" (358). Greenville lies next to the Mississippi River, about 130 miles southwest of 'Jefferson,' that is, Oxford, Mississippi. By using Greenville as the westward marker rather than, say, Clarksdale, which is 70 miles north of Greenville and still south of Oxford, Faulkner makes it harder to pinpoint the location of his imaginary county.
