Footnotes ...
| <1> | Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Rock City) to Point B. In other words: 'As the crow flies'. |
| <2> | If we encounter the name of what might be a community, our methodology is to add that name to our Gazetteer as a placeholder. As we find more information about that community, it will be added to our Gazetteer.
Just as a reminder: Our definition of a community is rather broad and includes those places (or areas) where several families lived and had a name which identified that place. For example, you might hear somebody say that they are going over to Bird Creek to see Pete ... Bird Creek is just a gas station and a couple of homes at the crossroads. While it might not be on the map, everybody in the area knows it by that name.
Places of interest include buildings at a crossroad, several families clustered in a hollow or maybe the location of a way station. It also includes places like mines, lumber camps, ferry crossings, etc. The community might still exist, is now gone or only existed for just a short period of time.
Also keep in mind that Rock City could have been on the original document by mistake, misspelled, the original/alternate name of a community that we've listed elsewhere or was placed in the wrong county. Sometimes a post office or train station would have a different name than the community where it's located, so two names might be referring to the same community - we're working to straighten it all out. |
| <3> | While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program. |
| <4> | While we have tried to pick reasonable speeds, the rate of travel is very theoretical - obstacles like fences, hills, lakes, river crossings and rest stops have been ignored. When we say 'Days' of travel, we're assuming 8 hours of travel per day. |
| <5> | The shortest line can be visualized by stretching a string on a Globe from Point A to Point B - this is known as a Great Circle Route. Where you might expect the shortest route from Rock City to the Middle East to be East and South, the Great Circle Route actually lies to the North and East.Our distance measurements begin at a specific point in Rock City. The point we use is located at these GPS coordinates - Latitude: 37.8496, Longitude: -121.9355 In this case, the coordinates for Rock City have been provided by the Geographic Names Information System (GNIS). |
| <6> | The calculated bearing (or angle) to Jerusalem is 339.803 degrees. |
| <7> | The calculated bearing (or angle) to Mecca is 340.677 degrees. |
| <8> | The calculated bearing (or angle) to the Vatican is 327.868 degrees. |
