Color is not claimed as a feature of the mark.
The mark consists of an image of a cut log of wood with the circular portion facing forward. On top of the log is an outline of a fire flame. The phrase NORTHERN, in stylized, cursive font is written across the image, positioned diagonally, at a slight angle, left to right. Below the word is the phrase FIRES in all capital letters, placed in the lower part of the log image.
