Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Caldwell) to Point B.Our distance measurements begin at a specific point in Caldwell. The point we use is located at these GPS coordinates - Latitude: 48.9717, Longitude: -108.1726 In this case, the coordinates for Caldwell have been provided by the Geographic Names Information System (GNIS).
