Frankfort Kentucky USA Horizontal Dial 90
The Kentucky Vietnam Veterans Memorial features a 7090 square foot plaza with a monumental 86x68 foot horizontal dial of granite slabs with a 14.6 foot high gnomon of welded stainless steel plates. The dial design places the shadow of the tip of the gnomon on each of 1103 veteran's names on the anniversary of his or her death. MIA names are engraved in an area where the shadow never falls. The dial face identifies one hour of time for each year of the 1962-1975 Vietnam War. The 327 granite slabs from the Pyramid Blue quarry in Elberton, Georgia are a maximum of 12x3 feet, are 4 inches thick and are placed atop 800 concrete piers 28 inches high to provide drainage and protection from frost heaving.

Quebec Quebec Canada Vertical Dial 87
Vertical dial on a board, about 1.5m high by 1 m wide. White with red lettering. It is placed above a doorway on an interior courtyard of the old Seminary, founded in 1663 by Mgr de Laval.

Stratford Connecticut USA Vertical Dial 86
Large vertical dial at the Shakespeare Festival Theatre entrance. The dial is formed around a large circular sunburst with Roman numerals at the edge. Gnomon is missing. Dial declines east and is non-functional for this position and location. Above the dial is a shield. The original sundial was a gift of US Time Corp., as Timex was then known. This dial was of sheet metal and is substantially rusted, with pieces missing. The original dial was removed and will be replaced as another gift of Timex with a new dial built by Global Scenic Services with engineering and testing by a Timex engineer. The new dial will use templates from the original dial for replication but is built with modern materials for better weathering. The new dial will be calibrated for EDST.
 
 
Storrs Connecticut USA Pillar Dial 85
Waugh memorial dial. Not oriented on cardinal points. It was rotated to avoid tree and adjacent building shadows. Gift of Mr. & Mrs. Kenneth Lynch Sr., the Alumni Association, and funds raised for the purpose. The stone pillar is 12 ft. high. Constructed by the firm of Kenneth Lynch & Sons.
 
 
Pomfret Connecticut USA Pillar Dial 84
A 22 ft. high stone pillar dial built by William Ross Carpenter as a replica of the famous Charles Turnbull dial of Corpus Christi College in England dating from 1577. The pillar has multiple dials of various types. The Carpenter replica built in 1912 was restored in 1987. Ornate dial furniture with multiple inscriptions. A complex masterpiece. See the NASS Compendium Vol. 2 No. 1 for more details.
 
 
Newington Connecticut USA horizontal Dial 83
Bronze horizontal ring, suspended by curved semi-circles, with gnomon rising from the center toward the North. "...you can see resemblances to an anchor, a gimbal, and a mariner's compass" says designer Searle Lansing-Jones.
 
 
San Francisco California USA Horizontal Dial 82
Built in 1913 as a promotion for a housing development that was once a racetrack, this dial boasted (incorrectly) that at 34 feet in diameter and 28 foot gnomon it was the largest dial in the United States. Nevertheless it gathered much publicity and newspaper articles of the day showed young girls dancing around a small pool that surrounded the gnomon. Bronze statues of porpoise were said to be in the pool. Today the statues are gone and the pool is green painted cement. Still, an interesting dial to visit.
 
 
Aurora Colorado USA Equatorial Dial 81
A large Erickson Monument equatorial polar dial 6 feet in diameter made of light granite with a 3 inch steel rod as gnomon. The dial was dedicated as part of the bicentennial celebrations in July 1976. Hour lines from 4am to 8pm. Time is graduated by half-hour, quarter hours and 5 minute marks. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. A plaque provides the Equation of Time to convert solar time to watch time. Dial has both the bicentennial emblem and the city seal of the city of Aurora.
 
 
San Diego California USA Vertical Reclining Dial 80
This dial was originally owned and installed at Sea World in San Diego but was sold and purchased by Verlyn Kuhlmann. A 39 inch diameter reclining vertical dial of cast concrete with a 20 inch long steel gnomon. Dial reclines about 50°. Includes cast hour lines with Arabic numerals and longitude correction. A separate plaque provides instructions and an EOT graph. The dial is mounted on a 24 inch square aluminum base plate and short column support.
 
 
Huntington Beach California USA Vertical Dial 78
A 7x8 foot direct south facing vertical dial of wood with metal gnomon on the masonry stucco side of a fire station building. Hour lines are painted on wood planks bolted to the side of the building. Metal Arabic DST hour numerals are mounted to the wood planks. Longitude correction is not included and there is no EOT correction or instructions offered but dial is accurate when both corrections are applied. When built in 1978, the hour numerals marked Standard Time; when rebuilt sometime before 2010, the new hour numerals now mark daylight saving time. The fire station building wall declines approximately 18.5? east of south but the wall area holding the dial has been built out to correct (perhaps not quite enough) this angle.
 
 
Los Angeles California USA Equatorial Dial 77
A bronze equatorial ring dial with taut wire gnomon on concrete pedestal. Ring is inscribed with hour, ten-minute and minute lines. Plaque states the dial indicates correct watch time so observatory staff periodically rotates clamped ring to correct for EOT, longitude and DST. Dial is located adjacent to the Astronomers Monument atop which is a large bronze armillary. The monument recognizes Hipparchus, Copernicus, Galileo, Kepler, Newton and Hershel. The sundial was originally built into the base of the Astronomers Monument but was relocated a few feet to the south during the 2002-2006 remodeling to allow visitors to more closely approach the dial. The dial sits atop a concrete pedestal.
 
 
Death Valley California USA Vertical Dial 76
Prospector and con man Walter Scott convinced Chicago millionaire Albert Johnson to invest in his gold mine in the Death Valley area. The mine was a fraud, but Johnson began building his Spanish Revival Villa in 1922 that continued until the stock market crash of 1929.

Johnson Vermont USA Horizontal Dial 71
One of Kate Pond's first dials, a winning design for an 18 foot diameter dial that now resides on the Johnson State College green. Concrete, Stainless Steel. On the ground concrete paths mark the N-S and E-W axes. The gnomon is a 3 inch stainless steel pipe 9 feet long attached to a concrete base. The hours are marked with 1 foot diameter Vermont granite stones, and at the cardinal points are larger stone markers. Kenneth Leslie, Assistant Professor of Art, remarked, " I have the idea of a student sitting against the North marker, reading a newspaper for a noon class, and knowing it's time to leave when the shadow crosses his paper."
 
 
Jerico Vermont USA Horizontal Dial 70
50 foot diameter horizontal dial of steel, concrete and stone. Called "Polaris". The gnomon is 10 foot high forming a stone pyramid.

Amarillo Texas USA Gnomonic Dial 67
The Centennial Time Tower begins as a tetrahedron of stainless steel pipes each 18 feet long. Then a central pipe towers to the sky, giving an overall height of about 50 feet. The Time Tower is situated on a circle about 100 feet in diameter. The dial was erected for the hundredth anniversary of the discovery of Helium. Each individual pipe is a time capsule filled with helium. The plaque under the center of the tower shows when each one is to be opened.
 
 
Trois Rivieres Quebec Canada Vertical Dial 66
A declining vertical dial approximately 6 feet wide and 8 feet tall of painted wood. Diol declines 58? west of south. Dial includes a two-lined analemma noon mark that shows noon corrected for EOT. Hour lines with Roman numerals show local time from 10 AM to 7 PM. Dial is located about 30 feet high on a wall, above an alcove with a statue of the Virgin Mary. The gnomon length is correct for the shadow of the tip to fall on the noon mark. Dial furniture includes a lunar crescent and a depiction of a beaver carrying a tree branch, in a classic French tradition and similar to dials of Zarbula's overall design.
