New York New York USA Armillary Dial 248
The armillary dial is 30 inches in diameter, built of bronze with a cast stone pedestal. On the outside of equatorial band are golden zodiac signs. Inside the band are roman numerals for hours from 6 am to 6 pm. The dial was vandalized but was refurbished in 2000 and moved a short distance in Parks Dept. renovation. Sal Ton Landscape was the general contractor; Kenneth Lynch & Sons repaired the sundial and made a complete new cast stone fluded base in 2000.
Queens New York USA Horizontal Dial 247
Paul Manship was commissioned to make the sundial for the 1939 World's Fair in New York. The dial was named "Time and the Fates of Man." Manship wrote, "The Perisphere and Trylon at the World's Fair suggests to me measurements of time and space, so my sundial… relates to the background of the central motif of the Fair." His white plaster sculpture was the biggest sundial in the world, standing 80 feet tall.
Queens New York USA Vertical Dial 246
A vertical dial on the cupola above the main entrance. Declination 70° 12' 04" E. Painted all white so that no hour lines can be seen.
New York New York USA Vertical Dial 245
3 x 4 feet bronze vertical declining S 28° W, 30 feet above the street level.
Houston Texas USA Armillary Dial 244
A 72 inch painted steel armillary dial with meridian, equatorial, horizon, Arctic and Antarctic rings. Equatorial ring has hourly Roman numerals and zodiacal symbols on its exterior. A bronze plaque on the base explains the armillary operation and provides a table of combined EOT and longitude corrections. Since Houston is more than 5 degrees from the time zone meridian, the longitude correction is almost 22 minutes, greater than the largest EOT correction, resulting in the combined corrections to always add to the dial time. Dial is mounted to a two foot diameter concrete pedestal. This dial was restored in 2000 by the Houston Municipal Art Commission funded by Searcy and Elizabeth Bracewell.
Baltimore Maryland USA Vertical Dial 243
18 x29 inch vertical dial. Solar noon analemma, equinox and solstice lines, horizontal lines, line showing approx shadow lengths on April 15 and Aug 31. Lines sandblasted into veined white Carrera marble. Dial is calibrated for EDT. AM hours indicated by shadow of stile's western edge, PM, by shadow of its eastern edge. When shadow tip is bisected by appropriate seasonal segment of the line of the analemma, it is 1:06:35 PM.
Goldendale Washington USA Equatorial Dial 242
The sundial has a 53-inch semicircular steel equatorial ring and is 18-inches wide. The 18-inch rod gnomon is suspended above the dial by two horizontal rods. A small cross-bar in the middle of the gnomon acts as a nodus for telling the date. A mechanical adjustment allows for the equation of time correction. The dial is mounted on a large boulder on the Northwest end of the Goldendale Observatory close to the Solar Telescope Building.

Pekin Illinois USA Horizontal Dial 233
A unique horizontal dial using both a sloping 15 foot aluminum gnomon and much taller 45 foot vertical pole. The ground level dial face consists of seven analemmas drawn in the grass field that surrounds the dial center. The analemmas are drawn for the hours 8-AM to 3-PM 3, corresponding to the tip of the sloping aluminum gnomon. However, the noon analemma is larger and corresponds to the shadow of a disk atop the vertical pole. The board of directors for the Pekin Park District offered a large place in the Mineral Springs Park Sunken Garden for Henry Cakora's desire to build a sundial. Henry designed and cast the dial, and the dial was built with assistance from local contractors and individual volunteers.
Santa Barbara California USA Equatorial Dial 232
A small bronze equatorial dial made by Victor E. Edwards in the 1920's. It has an unusual crescent shaped arm with notch at the upper end.
