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 Grand Island, please let us know so that we can improve our accuracy.
<2>If you're interested in how the shape of Colorado's counties, including Boulder, have changed over time, we recommend the Atlas of Historical County Boundaries.
<3>A demonym is the name for a resident of a community which is usually derived from (or is related to) the name of that community. In other words, it's how the residents of Grand Island refer to themselves. It's important to note that there aren't any rules for taking a community's name and turning it into a demonym. A demonym is informal and while the majority of Grand Island may use one name, keep in mind that others may use something different.
<4>The elevation is an estimate for the area around Grand Island - it will be higher in some places and lower in others.
<5>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 303 code has been Overlayed with the 720 area code. New phone numbers in the Grand Island area will be assigned with one of these codes: 303 or 720. As a result, placing a call in the Grand Island area will require 10-digit dialing (where you enter both the area code and then the phone number).
<6>While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<7>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.
