Magisterial District Map and Descriptions
Note the large number of homes in the Enterprise - Hayward area
on the map at the above link. Today, all but a few are gone.
Also, the old rail line from Carter City toward Vanceburg.
Old Route 60 makes a circuitous route around Everman Hill between Olive Hill and Globe.
The pre-Interstate 64 road routings north of Grayson are also shown.
I believe the black boxes with little pennants on them are schools (at first I thought they were Post Offices).
Some churches appear to be a box with a cross.
Somehow the eastern portion of the county (Magisterial District 7: Denton, Rush, Williams Creek) got left off this map.
