Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance starting from Iknetuk. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Iknetuk) to Point B.
Our distance measurements begin at a specific point in Iknetuk. The point that we are using is located at these GPS coordinates - Latitude: 64.4667, Longitude: -163.0667 [Map]. In this case, the coordinates for Iknetuk have been provided by the Geographic Names Information System (GNIS).
