Our distances are not driving distances, but are calculated as a 'straight-line' distance starting from Kustatan. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Kustatan) to Point B.
Our distance measurements begin at a specific point in Kustatan. The point that we are using is located at these GPS coordinates - Latitude: 60.7158, Longitude: -151.7475 [Map]. In this case, the coordinates for Kustatan have been provided by the Geographic Names Information System (GNIS).
