Footnotes ...

<1>If you're interested in how the shape of Idaho's counties, including Owyhee, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The pronunciation we've provided is our attempt to give a phonetic pronunciation for Grasmere. While it might not be exactly right, hopefully it will be close. If we have it wrong or there's a better way to pronounce the name, please contact us through our Feedback Page.
<3>The elevation is an estimate for the area around Grasmere - 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 208 code has been Overlayed with the 986 area code. New phone numbers in the Grasmere area will be assigned with one of these codes: 208 or 986. As a result, placing a call in the Grasmere 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.
