Fort Wayne Indiana USA Equatorial Dial Dial 956
According to WPTA-21 news, "This odd looking nine thousand pound chunk of limestone is a scientific instrument, a sundial unlike any you’ve seen." It is an equatorial dial but with a parabolic shaped equatorial for telling time. The reason for the odd shape? "The shadow cast by a stainless steel bar moves across the dial face telling time not just in Fort Wayne but also half a world away in Takaoka, Japan, one of Fort Wayne’s Sister Cities. A half-size version of the same sundial in Takaoka does the same thing."

This equatorial dial is improvised using a 13 inch diameter aluminum plate embossed with fleur de lis around the perimeter. Hour lines run from 6am to 6pm with Arabic markers only at 12 and the 6's.
Saratoga Springs New York USA Horizontal Dial Dial 954
The beautifully engraved horizontal dial plate is a reproduction of the original 1901 dial. It is inscribed with “Lat 43 degrees 5 N, Long. 73 degrees 46.40 W.” This is at slight variance from the current GPS position, implying that the dial has been moved from its original position. The dial plate is 18 inches in diameter and the gnomon has a vertical height of 8.5 inches. The gnomon and dial plate are aligned at 12 degrees west of true north. Significantly, the compass magnetic declination for this location is 13.5 degrees west of true north. This misalignment makes the dial about 30 minutes fast. This is particularly unfortunate since the inscribed dial is capable of showing time to the nearest minute. The stone table upon which the sundial rests is a reproduction of a table found in the ruins of Pompeii.
Calgary Alberta Canada Armillary Sphere Dial 953
