Caves in Hills in "The Unvanquished" (Location)

During the reign of terror that Grumby's gang inflicts upon Yoknapatawpha, the group that Bayard refers to as "the Negroes who had lost their white people" - that is, former slaves whose place on the county's plantations has disappeared during the Civil War - "live hidden in caves back in the hills like animals" (93). There are hills both east and west of Jefferson but this is the only reference to these "caves" in the fictions, so we have had to guess where in the county Faulkner imagines them.
