Description:
  • This is a rare American stained glass sundial, accurately telling time and season. It occupies the center panel of a five panel window that forms a cross. The vertical sundial panel measures 28x28 inches and declines 48° west of south, so it only functions in the afternoons. The dial is longitude corrected and indicates Daylight Saving Time when readings are adjusted using the Equation of Time. The gnomon is a 3/4 inch brass ball nodus attached by a non-polar axis rod to the aluminum Sussman window frame. It is the only stained glass sundial in the world that uses frosted colored stained glass to enhance the view of the nodus shadow. It has three seasonal date lines, a solar noon mark, and other marks showing special anniversary dates. It contains the traditional fly, seen on the the lower yellow panel between 1pm and 1:30pm.

    It took exactly one year to design and build all five window panels. Shadow tests showed that frosted (sandblasted) stained glass produces shadows that are sharper and crisper than opalescent glass. It is the first stained glass window that uses frosted colored glass for the shadow. John Carmichael worked closely with Ron Wood who lead the effort to get the window built. Carmichael states."I consider this to be one of my best sundials. It certainly was a great fun challenge to design, build and install. Its photo appears on the cover of the new Camp Song book."
