It is in the public domain, as it was created by the US Government, and then, using the Microsoft Office "Paint" program, I personally made the red triangle and the words denoting the region as the Red Triangle. I release any and all rights to the public domain in perpetuity forevermore.
This map image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Northern California red triangle.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
