Oro Valley Arizona USA Combination Dial 713
A massive, 24 foot tall combination almost-vertical and calendrical dial facing southwest so that northeast bound traffic can easily view the dial. The 13 foot diameter vertical ring dial of welded, zinc-coated steel declines 45? west and reclines 12? from vertical. The 3 inch diameter, 20 foot long polar-pointing gnomon tube is supported in space by a 10 inch diameter support tube with a cone nodus on the bottom end. The vertical dial shows longitude-corrected MST with hour and half-hour marks and Arabic numerals on the outer stainless steel chapter ring. The calendrical dial solar noon line is a bronze plaque atop a triangular, fin-shaped concrete pedestal and inclined at the latitude angle, allowing the equinox mark to be in the center of the date line with the indicating shadow cast by the cone nodus on the bottom of the gnomon support tube. Other significant dates indicated include the solstices, date of dial dedication, date of Oro Valley incorporation and the date of Arizona statehood. As of July, 2012 the date line of the calendrical dial remains fully designed but incomplete and uninstalled so this portion of the dial is not functional. Dialist John Carmichael reports this is the most difficult and complex project he has designed. The dial base is a modern sculpture of welded steel plates by artist Jon Seeman. This 10,600 pound monumental dial was three years in design and fabrication.
