Adding Mount Ophir to Our Gazetteer ...

As we work on our Gazetteer, we occasionally find mention of a community that is new to us. When we find such a community, we add it to our Gazetteer with the hope of adding more information in the future.

The earliest source we've referenced which mentioned Mount Ophir was in the document titled List of Post Offices from Cameron Blevins and Richard Helbock.<4>

From that list, the Mount Ophir post office opened in 1856.

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 Mount Ophir, please let us know so that we can improve our accuracy.
<2>	If you're interested in how the shape of California's counties, including Mariposa, have changed over time, we recommend the Atlas of Historical County Boundaries.
<3>	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 209 code has been Overlayed with the 350 area code. New phone numbers in the Mount Ophir area will be assigned with one of these codes: 209 or 350. As a result, placing a call in the Mount Ophir area will require 10-digit dialing (where you enter both the area code and then the phone number).
