Do you know of Grand Valley ???

This page is an orphan - a placeholder until we can discover more about Grand Valley. When we encounter a name that is new to us, we add it to our Gazetteer with the hope that we'll discover more information in the future. Such is the case with Grand Valley.<1>

We found mention of Grand Valley as a post office (see Mentions and References below), but can't determine its location - other than being located somewhere in Corson County, South Dakota.

It's common that the post office is named the same as the community in which it's located (although that's not always case). In this case, we can't match this post office to any of the existing communities in our gazetteer.<2>

From the Blevins / Hellbock List: The post office opened in 1911 and closed in 1933.

Footnotes ...

<1>	This entry could have originated in error. It might be that a source had a misprint, was simply wrong or we made a transcription error while referencing it. Many of the documents we reference are from the 1800s and the early 1900s, with some easier to read than others.
<2>	Part of the difficulty in identifying whether a name is a post office or a community lies with how Post Offices were named. We've prepared an article with our understanding of how post offices were named: Naming of Post Offices.
<3>	If we encounter the name of what might be a community, our methodology is to add that name to our Gazetteer as a placeholder. As we find more information about that community, it will be added to our Gazetteer. Just as a reminder: Our definition of a community is rather broad and includes those places (or areas) where several families lived and had a name which identified that place. For example, you might hear somebody say that they are going over to Mile's to see Pete ... Mile's is just a gas station and a couple of homes at the crossroads. While it might not be on the map, everybody in the area knows it by that name. Places of interest include buildings at a crossroad, several families clustered in a hollow or maybe the location of a way station. It also includes places like mines, lumber camps, ferry crossings, etc. The community might still exist, is now gone or only existed for just a short period of time. Also keep in mind that Grand Valley could have been on the original document by mistake, misspelled, the original/alternate name of a community that we've listed elsewhere or was placed in the wrong county. Sometimes a post office or train station would have a different name than the community where it's located, so two names might be referring to the same community - we're working to straighten it all out.
