Description:
  • An unusual dial by John Carmichael using a "Point in Space" gnomon; only the shadow cast by the tip of the 6 inch angled rod gnomon is used to indicate time. The dial face is poured concrete with inlayed metal longitude-corrected hour lines, and is nearly horizontal, inclining just 1.27 degrees for water drainage. It declines 89.28 degrees east of south. Bronze plaque has User Instructions and an Equation of Time Graph. Dial functions best during the middle part of the day. The style shadow lies outside of the dial face boundaries in the early mornings and late afternoons. The massive elaborate base that supports the gnomon rod is made from stacked flagstone. A waterfall cascades from the back south side of the base and flows a long distance to the south through a canal that has several water fountains and pools along the way. Around the base is a planter with bedding plants. The base and gnomon are lighted at night.
