Northern Bay Newfoundland Canada Armillary Dial 789
An approximately 24 inch diameter steel and aluminum armillary dial with wrought iron scrollwork base. The equatorial ring includes an aluminum plate inscribed with hour, half-hour and five minute marks showing time from 5 AM to 7 PM. A plaque on the pillar below shows combined corrections for EOT and longitude. The dial is mounted on a 10 inch fluted concrete pillar, reinforced with steel rebar.
 
 
Norwich Connecticut USA Horizontal Dial 546
A well-patinaed horizontal dial placed atop a stone column. Dial sits atop a cast aggregate column.
 
 
Norwich Vermont USA Horizontal Dial 630
A 12 inch square gray granite horizontal dial with bronze gnomon on a terracotta and stucco pedestal. Corrected for longitude to read EST. EOT corrections to nearest half-minute for the 1st and 15th of each month are engraved on edges of dial face. This is a private dial, not generally available for viewing. Dial sits atop a post of terracotta covered with stucco.
 
 
Oak Bay British Columbia Canada Horizontal Dial 738
A 10 inch square brass or bronze horizontal dial atop a 22 inch square concrete base with cross-shaped plinth 42 inches high. The natural patina developed by the corrosive sea air has reduced the contrast of the markings. Stylized Arabic hour numerals are engraved in circles. Engraved scrolls add interest but some confusion to the dial face. The dial face and gnomon are only one-eighth inch thick but remain intact.
 
 
Oakland California USA Sculpture Dial 307
Bronze sundial sculpture by Robert Paine. The sundial was donated to University High School in 1927 by Sara Bard Field in honor of her son Albert, who was killed in 1917 in an automobile accident. Albert was the high school senior class president in 1917. His mother Sara was a leading suffragist on the West Coast. The High School has been renovated and now used by Children's Hospital Oakland Research Institute (CHORI). The sculpture is of a boy holding a shield and an arrow. The arrow casts a graceful shadow onto the level shield. The sculpture is about 30 inches high. The base is stone, probably a jade.
 
 
Oakland California USA Projection Dial 613
One of Bill Gottesman's unique-design Renaissance dials of cast and structural bronze with a 27 inch diameter helix with a celestial-north aligned axis. Time is told by a focused beam of light that moves around the helix throughout the day. The light beam is reflected from a long cylindrical unsilvered mirror in a structure that supports the helix. A sliding time scale within the helix can be adjusted for EOT and DST and includes longitude correction. Once this scale is adjusted for date, the dial shows civil, or clock, time. The dial base is cast bronze allowing adjustment for latitude and placed on a concrete pedestal.
 
 
Oakland California USA Horizontal Dial 236
Large horizontal dial, with steel gnomon 22 ft. long, 14 ft. high. Constructed of three welded pieces of 2-inch thick steel plate, the dial sits in a courtyard. There are no hour lines, only hour markers are placed on the lawn and brick patio around the dial. EOT values for every 5 days are shown on the north face of the support.
 
 
Oberlin Ohio USA Calendrical Dial 63
When is a flag pole more than a flag pole? When it has cement walkway curved for the summer solstice, a path for the winter solstice and a distinguishing straight cement line for the spring and fall equinox. This dial has no hour markers, and is intended to show the seasons. The tip of the flag pole will follow these lines at the appropriate day of the season.
 
 
Oberlin Ohio USA Vertical Dial 219
Once, high on the physics building south wall was a student made vertical dial. The 5'x8.5' resin coated particle board made by Mark Kearns in 1979 had curved hour lines to account for the equation of time, declination of wall, and offset from standard meridian. This dial has not been on display for some time. Perhaps some student would create a new dial. The brick wall is an excellent location.
 
 
Ocean Shores Washington USA Horizontal Dial 842
This large horizontal dial has a gnomon in the shape of an anchor and concrete minimalist dial surface in the shape of a triangle, keeping the theme of the location "Triangle Park". Three time Arabic hour numbers of 9, 12 and 3 are embedded into the concrete slab and two other time marks of 6am and 6pm are on separate pads located outside the main dial area.
 
 
Oliver British Columbia Canada Horizontal Dial 809
A lovely horizontal dial with an 8-foot high stainless steel gnomon. The hour lines are done as colorful alternating red and cream segments set in a 8-foot radius semi-circle. The gnomon is triangular in cross section with a single thin edge casting the shadow. The dial hour numbers are set for daylight, since all of the winery's 100,000 annual visitors are seasonal, coming when Pacific Daylight Time is in place.
 
 
Olympia Washington USA Horizontal Dial 319
John W. Elliot, a Seattle master craftsman designed and execute the Territorial Sundial. The 6 foot dial is hand-hammered in brass with a bronze rod gnomon. The dial plate has eight bas-relief panels depicting events in Washington State's history including the discoveries of Captain George Vancouver in 1792, the Medicine Creek Treaty between the US and Puget Sound Native Americans in 1854 and the first railroad to Puget Sound, built in 1883. The dial rests on a large slab of Wilkenson sandstone, the same material used in the nearby State Library, supported by four, one foot nine inch tall piers.
