Our distances are not driving distances, but are calculated as a 'point-to-point' distance beginning in Ophir. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Ophir) to Point B.
Our distance measurements begin at a specific point in Ophir. The point that we are using is located at these GPS coordinates - Latitude: 63.1447, Longitude: -156.5194 [Map]. In this case, the coordinates for Ophir have been provided by the Geographic Names Information System (GNIS).
