Our distances are not driving distances, but are calculated as a 'point-to-point' distance that stretches from Park Hill. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Park Hill) to Point B.
Our distance measurements begin at a specific point in Park Hill. The point that we are using is located at these GPS coordinates - Latitude: 33.5965, Longitude: -86.2861 [Map]. In this case, the coordinates for Park Hill have been provided by the Geographic Names Information System (GNIS).
