Our distances are not driving distances, but are calculated as a 'point-to-point' distance starting from Powell. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Powell) to Point B.
Our distance measurements begin at a specific point in Powell. The point that we are using is located at these GPS coordinates - Latitude: 34.9779, Longitude: -87.2536 [Map]. In this case, the coordinates for Powell have been provided by the Geographic Names Information System (GNIS).
