<1> | Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Riffe) to Point B.Our distance measurements begin at a specific point in Riffe. The point we use is located at these GPS coordinates - Latitude: 46.5140, Longitude: -122.3704 In this case, the coordinates for Riffe have been provided by the Geographic Names Information System (GNIS). |
