Footnotes ...

<1>If you're interested in how the shape of South Dakota's counties, including Fall River, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The elevation is an estimate for the area around Dennis - it will be higher in some places and lower in others.
<3>The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required.
<4>While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<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.
