Farrell Pennsylvania USA Sculpture/Artwork Dial 519
"Rising Rings" is a cast iron band 11 feet high by 17 feet in diameter with a hole that casts a beam of light onto a central ring monument on the equinoxes. The dial was commissioned by Dr. Swraj Paul, a steel mill owner, to honor his daughter Ambika who died in 1968 of leukemia at age four. This monument honors the inspiration her joy of life instilled in her father. At the central of the dial is a cast iron ring that holds a bronze image of her that is illuminated for several days twice a year. On two dates, Ambika's birthday and the anniversary of the mill's re-opening the noon sunlight passes through the circular opening in the larger ring and strikes markers on the inner ring. Miklos Simon created the portrait of Ambika mounted on the smaller ring.
 
 
Redding California USA Horizontal Dial Dial 518
When is a bridge not a bridge? When it's almost a sundial. The 217 foot high suspension span called Sundial Bridge wants to be a sundial, and has come very close. The suspension pylon is aligned true north, but unfortunately performs as an inaccurate gnomon with an inclination of 49 deg (for bridge functionality) rather than for the 40.6 deg latitude of the site. The bridge is 700 feet long and weighs 1,600 tons. Funding for the bridge comes from the McConnell Foundation, Redding Redevelopment Agency, Federal Highway Administration, and Turtle Bay Exploration Park

Montour Falls New York USA Horizontal Dial Dial 516
A beautiful bronze dial approximately 12 inches long in the shape of a shield. Below the gnomon is a rising sun. On first look, the small dial plate appears backward, with AM and PM hours reversed.

The dial sits atop a circular granite pedestal about 2.5 feet in diameter.
 
 
Winter Park Florida USA Horizontal Dial Dial 515
A 12-inch diameter horizontal bronze dial set on a simple fluted pedestal. The dial face includes hour lines with half hour and ten minute marks and a central compass rose.

Nantucket Massachusetts USA Compound Dial Dial 513
A combination of horizontal dial and gnomonic projection dial. The dial is about 2 x 3 feet made of DuPont Corian sitting upon a simple wood pedestal. A small horizontal dial about 8 inches in diameter with a triangular brass gnomon tells Daylight Saving Time using Roman numerals. Then a larger gnomonic dial is inscribed on the remaining surface, telling time from the shadow of the tip of the triangular gnomon. The gnomonic dial has hourly analemmas,telling time using Arabic numbers in Standard Time. Both dial lines are offset for the longitude of 70 degrees west. The gnomonic dial has declination lines for each month. A small analemma on the meridian has the letters of the months, indicating how to read the hourly analemmas depending upon the date. The dial is built to be read from the north, so the user's shadow does not interfere.
