Footnotes ...

<1>If you're interested in how the shape of Washington's counties, including Lewis, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Winlock.
<3>The elevation is an estimate for the area around Winlock - it will be higher in some places and lower in others.
<4>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 360 code has been Overlayed with the 564 area code. New phone numbers in the Winlock area will be assigned with one of these codes: 360 or 564. As a result, placing a call in the Winlock area will require 10-digit dialing (where you enter both the area code and then the phone number).
<5>ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a city (such as Winlock). When looking for a ZIP Code, whether Winlock or elsewhere, it's always best to check the website of the United States Postal Service (USPS).

<7>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.
