Gallup New Mexico USA Horizontal Dial 568
An 18 inch diameter horizontal dial of welded steel with a naturally weathered rusty brown finish. The hour lines are corrected for longitude and summer and winter solstice lines are shown.
 
 
Galveston Texas USA Equatorial Dial 318
This is an equatorial dial 3 x 4 feet tall, set up for the latitude and longitude of Galveston Texas. Corrections for the Equation of Time are cut as an analemma into the broad gnomon that rotates on a polar rod. The Equatorial time ring has hour lines viewed as standard time or DST at 5 minute intervals. The dial started when one of the Galveston residents constructed a park to honor his grand father. Bill Swann proposed to put a dial in one corner. His friend liked the idea. The park architect wanted the dial to be long lasting and suggested that it be made of galvanized steel. The dial is made out of rolled flat bar with a cross section of 3/4 x 4 inches. The dial itself was patterned after a dial which was located at Swann's college campus- Vanderbilt University. That dial was designed by the late Professor Dillard Jacobs. While Swann did not remember the specifics of that dial, the memory of it set the quest to decipher the suns orbit for this Galveston sundial. The time is displayed from a shadow cast onto a time ring. The "operator" pivots a plate, facing it toward the sun. The inscription on the plate reads "Face bar towards sun-Read time at month's shadow". The plate has a cutout in the shape of the analemma. Where the shadow cast by this cutout falls on the time ring specifies the time. Swann remembers that he "stayed out quite late one night to align the dial to a point in the sky near the north star." The sundial design is identical to the design of dial # 344 on the NASS web page. The metal forming techniques are different. Swann has been in contact with the designer, Peter Swanstrom.
 
 
Gastonia North Carolina USA Horizontal Dial 649
A 56 inch horizontal dial of stone masonry with wrought iron gnomon. Dial center filled with crushed rock with Roman numerals on perimeter stones. Dial is longitude corrected to EST and the EOT correction is shown on an adjacent landscape stone. Dial is on private property but can be seen from the public street. For closer viewing, contact owner.
 
 
Georgetown District of Columbia USA Vertical Dial 798
A vertical dial, perhaps one foot square, above the front door of the Georgetown University Astronomical Observatory (the Hayden Observatory). The dial face has Roman hour numerals near its perimeter.
 
 
Gettysburg Pennsylvania USA Horizontal Dial 699
An elaborate gold-colored horizontal dial located on the front lawn of the Eisenhower National Historical Site. The dial was a gift of the National Watch and Clock Collectors. Dial face includes hour lines with Roman hour numerals and a poetic verse describing time.
 
 
Gettysburg Pennsylvania USA Horizontal Dial 700
A hexagonal bronze horizontal dial located on the rear lawn of the Eisenhower National Historical Site. The dial was a gift of the Radio and Television Correspondents Association. Dial face includes hour lines with Roman hour numerals and the inscription Tempus Fugit. The dial and a small plaque are mounted on a 120 mm artillery shell.
 
 
Gila New Mexico USA Polar Dial 541
An 8x4 foot painted plywood polar dial. Contact owner M. Cuff for access.
 
 
Glenwood Springs Colorado USA Analemmatic Dial 576
An 11x15 foot poured concrete human analemmatic dial with Standard and DST numerals, seasonal markers and an EOT plaque. The dial is located on the playground of an elementary school.
 
 
Gloucester Massachusetts USA Horizontal Dial 44
 
 
Gold Canyon Arizona USA Horizontal Dial 657
Built as an Eagle Scout project, this 10 x 5 foot semicircular concrete and steel dial features a 3 foot tall figure of a coyote as the gnomon. The tip of the coyote's nose functions as a point-in-space gnomon. The figure is placed well forward, limiting the times and dates the nose-tip shadow will fall within the hour circle to about 9 am to 3 pm on dates near the summer solstice.
 
 
Golden Colorado USA Reflective Equatorial Dial 855
This dial is one of Bill Gottesman's uniquely designed Renaissance dials of cast and structural bronze with a 27 inch diameter time telling helix whose axis is aligned to the celestial-north pole. Time is told by a focused beam of light from a long cylindrical unsilvered mirror situated on that N-S axis, reflecting sunlight into a slit of light onto the helix, telling time throughout the day. A sliding time scale within the helix is adjusted for longitude, date's equation of time correction and daylight saving time. Once this scale is adjusted for date, the dial shows civil (local clock) time with an accuracy of under one minute. The dial base is cast bronze that allows adjustment for latitude and is placed on a sandstone plinth.
 
 
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.
 
 
Grand Falls New Brunswick Canada Horizontal Dial 559
A horizontal dial using a 12 foot diameter blackened steel ring dial face and 8 foot high blackened steel gnomon. Dial face uses Roman numerals with XII at north.
 
 
Grand Forks North Dakota USA Armillary Dial 282
A large brass and cast iron armillary dial with full equatorial and equinoctial colure rings, two tropic rings and Arctic and Antarctic circle rings. The sphere is tilted so the central gnomon points to celestial north and is mounted in a four-legged stand. The gnomon includes a nodus that casts a shadow on a plate with engraved date analemma.
 
 
Grand Haven Michigan USA Equatorial Dial 601
A bronze equatorial dial approximately 6 feet high with bowstring gnomon. Hour markings show Daylight Saving Time and are longitude corrected. Dial sits atop a brick plinth.
 
 
Grand Rapids Michigan USA Horizontal Dial 287
A cast iron statue of a small boy painted in gold and kneeling. With arms upright, he holds a plate on top of his head that held the original sundial face, surrounded by an inscription and ornamentation. The statue is bolted to a concrete pedestal. With the original sundial gnomon removed, a new oversized horizontal dial has been carelessly bolted onto the top plate. The gnomon and dial face imply it is a British reproduction, totally unsuited for the Michigan location. The dial face is ornate, with a compass rose in the center, surrounded by a chapter ring divided in 15 minute intervals. A second, outer chapter ring divides time into 5 minute intervals. Time is indicated with Roman numeral hour marks. Dial in good alignment, but illuminated by the sun only during early morning.
 
 
Grand Rapids Michigan USA Analemmatic Dial 892
The brightly colored analemmatic dial is approx 10.5 feet in diameter, surrounded by a ring of alternating red and white concrete with cardinal points. Time marks are set in a ring of black concrete, with large engraved hour numbers. Time is adjusted for daylight saving time.[Note that to tell time correctly, the time marks should be set on an ellipse.] The walkway for standing to cast your shadow has monthly names impressed into the concrete.
 
 
Grande Prairie Alberta Canada Horizontal Dial 816
This monumental stainless steel sundial was built as part of the Grande Prairie Millennium Project. The beautiful gnomon is 12m (40-feet) tall and symbolizes the passage of the year 2000 into the 21st century. Behind the visible stainless steel cover of the sundial's gnomon is a one by two foot steel beam. Engineers adopted computer programming techniques to construct and align the 30 centimetre thick gnomon of the Centre 2000 sundial. Specific factors such as the city’s elevation, its latitude and correction longitude mark time with the region’s Mountain Standard and Daylight Savings Time.
 
 
Granville Ohio USA Horizontal Dial 528
This horizontal sundial is built on a one-meter cube of red granite with a cast bronze gnomon supported by a cast bronze Pegasus modeled by New York artist Carl Paul Jennewein. The dial's plaza location overlooks the village of Granville and the valley beyond to the south. The dial is a tribute to Clifford S. Stilwell (Denison Class of 1912) who was Chairman of the Denison Board of Trustees at his death in 1941. The early B&W photograph of the Pegasus gnomon is courtesy of Denison University Archives.
 
 
Graylake Illinois USA Stonehenge Dial 521
"Sun Pivot" is a set of vertical "gatestones" that allow the viewing of two major solar alignments: The summer sunrise stone is set about 33 degrees north of east while the equinox stone is set due east. The angular cuts in the gatestones allows the framing of the sunrise event above the stones, which are set about 200 feet away in a field of prairie grass.
