Our distances are not driving distances, but are calculated as a 'point-to-point' distance starting from Dawson. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Dawson) to Point B.
Our distance measurements begin at a specific point in Dawson. The point that we are using is located at these GPS coordinates - Latitude: 34.3040, Longitude: -85.9261 [Map]. In this case, the coordinates for Dawson have been provided by the Geographic Names Information System (GNIS).
