Our distances are not driving distances, but are calculated as a 'straight-line' distance starting from Makushin. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Makushin) to Point B.
Our distance measurements begin at a specific point in Makushin. The point that we are using is located at these GPS coordinates - Latitude: 53.7750, Longitude: -166.9858 [Map]. In this case, the coordinates for Makushin have been provided by the Geographic Names Information System (GNIS).
