Footnotes ...

<1>	We use the term 'Historic' broadly and it generally means that the community no longer exists. However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now. Unfortunately our sources of data have proven to be unreliable. If you can provide us with more specific information about Mason Valley, please let us know so that we can improve our accuracy.
