Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance from Nyac. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Nyac) to Point B.
Our distance measurements begin at a specific point in Nyac. The point that we are using is located at these GPS coordinates - Latitude: 61.0042, Longitude: -159.9406 [Map]. In this case, the coordinates for Nyac have been provided by the Geographic Names Information System (GNIS).
