Kelowna British Columbia Canada Shadow Plane Dial Dial 960
It is a large sculpture that acts as a shadow plane dial delineated at hourly intervals. The dial is about 3m high. It is made of mild steel with a concrete base, very precisely cut and installed. It shows local solar time, delineated at hourly intervals. Each shadow plane projects onto a small vane that has notches cut out, the number of notches indicating the hour. This dial is one of the earlier artworks by Alan Storey, a successful Canadian sculptor specializing in large-scale public art. The setting is a pleasant tree-lined courtyard at the center of the campus. in the years since the courtyard was laid out and the dial installed, the trees have grown large and cast shade on the dial. The best time to view the dial in sun is probably mid-morning, or in the winter when deciduous trees have lost their leaves.
 
 
Kamloops British Columbia Canada Horizontal Dial Dial 959
A simple horizontal dial consisting of a 6' gnomon made of black-painted steel tubes set in a circular concrete patio.The dial is located in a pleasantly laid out xeno garden (planted for arid conditions) with benches and a pergola. A riverside walk passes close by, and the whole area is designated for recreational and sports use. The gnomon is unusual for its plain industrial feel, and the use of wire mesh to fill in the gnomon's triangular substyle area. As well, the north end of the gnomon is formed by a pole that extends an extra 6' upwards, topped off by a weather vane.
 
 
Denver Colorado USA Noon Mark or Meridian Dial Dial 958
Description, a 1-inch stainless steel line set in the granite pavement marks the location of the 105th meridian in front of Union Station. The meridian line marks the center of the time zone called Mountain Time, and is 7 time zones "earlier" the Greenwich. MT = UTC - 7. Throughout the Denver metro area, Kalamath Street is the road that most closely corresponds to the 105th meridian. The current 105th meridian would have been known as the 30th meridian of the United States in the 18th and 19th century.

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."

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
This large armillary sphere stands about 2m tall and 1.5m wide. The dial is marked by roman numerals etched completely through the equatorial band.

The design of a slot mechanism allows the equatorial ring to be rotated by 15° for Daylight Saving Time. However there is no plaque for the Equation of Time correction to civil time.
 
 
Summerland British Columbia Canada Armillary Sphere Dial 952
A steel patinaed armillary sphere about 1.5m in diameter, mounted on a low boulder. The dial is marked by roman numerals etched completely through the thick equatorial band.

A ball at the center of the dial has outlines of the continents, reflecting its status as a representation of the Earth at the center of the celestial sphere. The design of a slot mechanism allows the equatorial ring to be rotated by 15° for Daylight Saving Time. A simple Equation of Time plaque attached the boulder has explanatory notes allows correction to civil time.
