  • The square 14.5-inch dial is made of while milk stone with graphics highlighted using lithochrome paint. The gnomon is made of stainless steel 303-alloy and has the letter P held between the base and style. The dial sits upon a square frustrum pedestal 3-feet tall, 24-inches square at the base, tapering to 17.5-inches at the top. The pedestal is supported on a 32-inch square base.

    The dial was made to commemorate the total solar eclipse that occurred at its location on Aug. 21, 2017. The gnomon's tip serves as a nodus that tracks the Aug. 21 declination line. Along the line are time marks for partial eclipse onset, totality, and end of the partial eclipse.
