Our distances are not driving distances, but are calculated as a 'straight-line' distance starting from Cohoe. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Cohoe) to Point B.
Our distance measurements begin at a specific point in Cohoe. The point that we are using is located at these GPS coordinates - Latitude: 60.3686, Longitude: -151.3064 [Map]. In this case, the coordinates for Cohoe have been provided by the Geographic Names Information System (GNIS).
