Footnotes ...

<1>	If you're interested in how the shape of Illinois' counties, including Saint Clair, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>	The elevation is an estimate for the area around Signal Hill - it will be higher in some places and lower in others.
<3>	When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 618 code has been Overlayed with the 730 area code. New phone numbers in the Signal Hill area will be assigned with one of these codes: 618 or 730. As a result, placing a call in the Signal Hill area will require 10-digit dialing (where you enter both the area code and then the phone number).

<5>	An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates. That said, we have some confidence that we have placed the marker near the actual location. A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace.
