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.

For closer viewing, contact owner.

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
Cast Iron A small boy kneeling, holding the sundial above his head with both arms.
 
 
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.
 
 
Great Falls Montana USA Equatorial Dial 61
A monumental bow-string equatorial dial of curved 4x6 inch welded steel I-beams forming a 14 foot diameter equatorial arc. Stainless steel Roman hour numerals 5 AM to 7 PM are welded to the arc. Metal for the dial was once used at Rainbow Dam and was formed and welded at Rainbow Powerhouse. This dial was the inspiration of Gary Trescott, a River's Edge Trail volunteer who planted hundreds of trees along the trail and helped improve the trail for many years. Gary died in June 2012 but his work on the sundial was continued by Dana Woodward (Gary's cousin), Doug Norwick and others.
 
 
Great Falls Virginia USA Horizontal Dial 633
A phosphor bronze horizontal dial whose face is 17.7 inches across four rounded cruciform arms. Designed, made and presented by Tony Moss to commemorate the establishment of the first English settlement at Jamestown on May 14, 1607. The most striking feature is the inclusion of reproductions of the King James Great Seal of the English Virginia Company. The "navette" (little boat) shape of the seal is also reflected in a similar shape for the dial itself. These "English" features are balanced by an American input in the form of the "Celebrate Virginia" logo and that of the local Analemma Society that co-funded the pedestal along with Fairfax County Park Authority. A unique rounded-cruciform shape encompasses all the above elements together with the NASS logo and appropriate inscriptions. The dial is calibrated in 3-minute intervals and quarter hours. Square classical pedestal in reconstituted limestone made by Haddonstone UK. Pedestal is placed in a paved and railed area around the dial. A remarkable steel "safe" is provided to protect the dial and pedestal from theft or damage.
 
 
Green Lane Pennsylvania USA Armillary Dial 262
About 38 inch bronze and copper armillary with three intersecting copper circles. Supported by small bronze figure, perhaps Atlas. Dial is supported on a base 19 inch high x 24 inch wide.
