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 Johnstown, please let us know so that we can improve our accuracy.
<2>If you're interested in how the shape of Montana's counties, including Cascade, 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 Johnstown 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 Johnstown may use one name, keep in mind that others may use something different.
<4>The elevation is an estimate for the area around Johnstown - it will be higher in some places and lower in others.
