Honolulu Hawaii USA Vertical Declining Dial 481
An elegant vertical declining and reclining dial built on the sloping face of a large lava boulder. Total size of the dial is 4 1/2 x 6 feet and uses a half-inch thick copper gnomon 6 x 10 inches. Hour lines and numerals at 9, 12, and 3 are of brass. The dial is corrected for longitude and was designed to fit its deep valley location and orientation of the boulder. Tradition holds that these rocks have spirits and must be treated with respect.
 
 
Houston Texas USA Sundial Sculpture Dial 275
An 85 inch high bronze sundial-like sculpture with elevated horizontal semicircular ring and steeply inclined bar up from base. Pegs and marks on ring suggest hour marks but design is wrong for location. Work is dedicated to exploration of space and has been relocated to a very shady area.
 
 
Houston Texas USA Dial 68
Large gnomon with a lens which focuses the noonday sun near the equinoxes. Hour lines built to compensate for equation of time.
 
 
Houston Texas USA Armillary Dial 863
The armillary sundial is part of the statue Hercules Upholding the Heavens. The statue portrays the ancient Greek hero Hercules performing the eleventh of his twelve labors, holding the heavens on his back for Atlas. The bronze sculpture is 1,650 pounds and over 10 feet tall. In 1917 Paul Manship was asked by Charles Schwab (Bethlehem Steel) to create this sculpture for his garden at his newly completed mansion.
 
 
Houston Texas USA Equatorial/Armillary Dial 683
A 32 inch partial armillary of anodized aluminum and steel with wide equatorial and horizon rings and with equinoctial colure, Arctic and Antarctic circle rings. The gnomon includes an aperture to project a solar image on the wide equatorial ring, which includes EOT corrections, graphic for date determination and Zodiacal symbols. Reverse of gnomon aperture includes the university crest. Horizon ring graphic shows time of sunrise/sunset throughout the year. Dial is partially shaded by surrounding trees. Dial sits on an approximately 4 foot high polished granite pedestal
 
 
Houston Texas USA Calendrical Dial 684
A large concrete, paving stone and standing stone calendrical dial with interior labyrinth. Outer ring shows NESW alignments. Four split standing stone portals are aligned for summer and winter solstice sunrise and sunset. An inner ring contains 13 trees representing the 13 cycles of the moon. The park in which this dial is located is designed with an aeronautical and archaeoastronomy theme. The circular forms of the parking lot and plaza are aligned with the crescent lake on a N-S axis while the stone portals viewed from the plaza center mark the summer and winter solstices.
 
 
Houston Texas USA Analemmatic Dial 686
A large analemmatic dial of paving stones, square limestone hour posts with Arabic hour numerals and polished granite date line. Hour numerals show Standard Time. Dial has a concrete border around perimeter.
 
 
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.
 
 
Howell Michigan USA Analemmatic Dial 788
A 16 by 20 foot, two-tone concrete analemmatic dial with 7 AM to 8 PM Arabic hour numerals on 12 inch round stamped concrete disks. Instructional and use information is shown on impressed lettering colored concrete plates.
 
 
Humboldt Saskatchewan Canada Equatorial Dial 560
An equatorial armillary.
 
 
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.
 
 
Indianapolis Indiana USA Horizontal Dial 276
A stainless steel and concrete vertical structure 33 feet tall. A stainless steel triangular tube, upright, with triangular and trapezoidal cut-outs, placed in the center of a concrete circle, with a sundial face but may not be functional.

Isles of Shoals New Hampshire USA Armillary Dial 97
Simple armillary dial about 2 feet in diameter sits on a triangular cut stone pedestal. The equatorial band has raised Arabic numbers at each hour. The hours are adjusted by 42 minutes to correct for zone time. The gnomon is an arrow rod of traditional fashion. The base supporting the armillary is a small hemisphere globe, with a map of the continents plainly visible. The armillary cuts the globe at the Greenwich hour line facing due north. The triangular granite stone pedestal was once part of the Captain John Smith Monument, commemorating him as the discoverer of the Isles of Shoals in 1610.
 
 
Ithaca New York USA Equatorial Dial 99
This 650 pound equatorial has an adjustment This setup enables the instrument to read clock time. making this a very precise instrument. The gearing rusted in 1980 and was refurbished: "The heart of the sundial's functionality, a roundish steel disc called a cam, was also replaced with a stainless steel, slightly better-functioning one, connected to an hour and minute scale by small, stainless steel cables via a pair of precisely designed pulleys." Thus the mechanical adjustment compensates the sun's irregular motion called the Equation of Time and shows civil not solar time.
 
 
Ithaca New York USA Horizontal Dial 463
A horizontal sundial made from a slab of stone approximately 18 x 24 inches. The hour markings are inscribed in the form of an arrow pointing to the 12 o'clock hour. The gnomon is a thin blade.
