Sebastopol California USA Globe Dial 522
The sundial is a cement globe of the earth 28 inches in diameter inclined at 40 degrees, a bit off the site's 38' 20" N latitude. The globe is oriented with the site longitude on the upper meridian so that shadows across the globe represent the true sun angle at that moment. A rod through the globe casts a shadow onto the north polar regions in the summer. At the southern end is a small equatorial dial with hour lines from 8am to 4pm.
Sebastopol California USA Vertical Obelisk Dial 428
This is a vertical obelisk 3 foot on a side and 9 foot tall. It is more of a sun calendar than a sundial. The tip of the obelisk's shadow is tracked by marks on a concrete pad on the ground. The summer and winter solstices and equinoxes are indicated by tiles set in the pad.
Senatobia Mississippi USA Vertical Dial 792
A south facing vertical dial placed above a window high on a wall of a high school. The dial face includes hour lines and Arabic hour numerals 6 AM to 6 PM. The dial is a separate plate affixed to the wall. The dial may be viewed from College Street side of the building.
Sheboygan Falls Wisconsin USA Horizontal Dial 550
A 20 inch octagonal dial of bluestone on a 28 inch high base. The gnomon matches the latitude angle and the hour lines are approximate for a generalized geographic area.
Sheridan Wyoming USA Horizontal Dial 840
This monumental horizontal dial is 15 ft. in diameter sitting on a foundation of poured concrete and rebar. The dial face is etched on 4 large granite slabs from Canada. The gnomon is a 6-inch diameter steel pipe 97inches tall with a welded nodus ball and a triangular sheet beneath the gnomon that has a sun and the school logo (a mountain range) cut into it casting projected images onto the sundial face.
Shoreline Washington USA Analemmatic Dial 796
An 8 foot diameter concrete and pebble analemmatic dial with engraved stainless steel inserts for central date line and simple instructions for use. The dial face is raised one foot on a fluted column above the perimeter concrete and stainless steel walkway and has stainless steel Arabic hour numerals for 6 AM, 12 PM and 6 PM. The walkway has stainless steel inserts showing hour lines, magnetic north, true north, winter solstice, equinox and summer solstice directions.
Shreveport Louisiana USA Horizontal Dial 138
Stone Dial vandalized. Gnomon missing, apparently knocked off with some damage to horizontal dial plate. Dial bears Roman numerals, from IV to VIII.
Sidney British Columbia Canada Equatorial Dial 682
A 20 inch diameter brass equatorial dial with equatorial, meridian and equinoctial colure rings. Gnomon has two nodus balls that may show solar position at solstices. Equatorial ring has 15-minute marks and Arabic hour numerals. The dial alignment needs adjustment for its current location. This equatorial/armillary dial in the garden of Bendt Fellenius is a family heirloom, a dial given to his grandfather Walmar Fellenius in 1946 in Sweden. The garden is private but the sundial is visible from the street.
Sidney British Columbia Canada Horizontal Dial 749
A 10 inch diameter horizontal bronze dial with hour lines, quarter hour marks and Roman hour numerals. The dial face includes a central compass rose. The dial sits atop a fluted concrete pedestal. The dial is gnomonically correct, designed for latitude.
Silver Bay Minnesota USA Horizontal Dial 227
A horizontal dial on the ground, with an hour circle about 12 feet. The gnomon is of steel, about 4 foot high. The gnomon is oriented to magnetic north. It is not an accurate device. Three boulders surround the dial and cut off the shadow much of the time. Gravel hour circle has rocks to mark the hours, but the rocks can be moved and are strewn all about. More suggestive of a dial than a real dial.
Skippack Pennsylvania USA Analemmatic Dial 650
A concrete and engraved brick analemmatic dial set in a garden of crushed rock.
Soap Lake Washington USA Dial Sculpture Dial 652
A monumental, 1-1/3 life-size bronze, steel and basalt rock sundial sculpture of a human figure with raised arm serving as a gnomon. The sculpture, "Calling the Healing Waters," depicts a young Native American couple as Father Sky and Mother Earth, sacred essence of rain and minerals connecting and bringing healing. Reflecting ethnic and historical themes, the winged warrior protects and comforts the maiden holding a catch basin for the healing waters. The sculpture was commissioned to honor the healing properties of the waters of Soap Lake.
Solvang California USA Vertical Dial 750
A cast or wrought iron vertical dial about 3 foot square painted black, prominently mounted at the roof line of the Royal Copenhagen Inn. The dial face has hour lines, half-hour marks and Roman hour numerals. The dial in not quite gnomonically correct as the building declines a few degrees west of south and the gnomon appears to be at 45? rather than 34.5?. The dial is visible from Mission Road. An interesting wind vane is seen on the roof peak above the dial.
Somerville Massachusetts USA Vertical Dial 441
This 5 foot x 7 foot vertical dial is painted onto the true south facing concrete wall of a commercial building. The gnomon and hour lines appear to be weathered copper or bronze. The hour lines are corrected for longitude, but may be in error by about 5 minutes. The dial is in relatively good condition, but the painted numerals are fading. The building itself has been in several hands over the last 10-15 years.
South Bend Indiana USA Combination Dial 710
A combination horizontal dial with nodus on its gnomon and a meridian projection dial located below. Horizontal dial face is 44 inches diameter and made of polished Chinese gabbro basaltic rock, reflecting clouds overhead and gnomon shadow, which shows location of solar noon on gnomonic projection map of the world on dial face. Gnomon is supported by curved triangular bronze arches. Gnomon nodus shadow shows location on map where sun is directly overhead while solstice and equinox lines indicate date. Hour markers show EDST by Roman numerals with ten minute increments by Arabic numerals and marks for one minute. Dial is supported on an octagonal limestone pedestal with French Gothic cathedral window design allowing viewing of meridian dial date line. Meridian dial is placed below the octagonal limestone pedestal whose French Gothic cathedral window design allows the noon date line to be seen. The date line is illuminated only at noon by sunlight passing through a slit orifice that extends 2/3 the way up the pedestal wall, indicating dates between summer and winter solstice by the end of the end of the bar of light. The entire combination dial sits on a plaza inlaid with three types of granite to form a 32 foot diameter compass rose, with sunrise and sunset times shown for sixteen dates special to Notre Dame University.
South Burlington Vermont USA Horizontal Dial 264
An 8 foot wrought iron steel horizontal dial. Design is of two circles enclosing one another and quartered. Outer circle is 11 foot wide with beaded edges and Roman hour numerals. Inner circle is 3'4" diameter quartered disk. Surveyed in 1992, finding condition very poor; steel dial is rusted. No motto or plaque is provided.
South Burlington Vermont USA Calendrical Dial 695
A calendrical dial sculpture of light beams projected onto the crushed stone surface of a 60 foot diameter meditative labyrinth. Two cylindrical focusing mirrors are located atop 10 foot poles and project short bars of sunlight that wander around the labyrinth but intersect on the equinoxes and winter solstice to form a cross at the center of the labyrinth at solar noon.
South Hadley Massachusetts USA Horizontal Dial 338
A small horizontal dial about 16 inches square, with a plain gnomon that rises about 6 inches. Nearby is a building with a hard to find wall dial, covered by ivy. Mayall's 1938 edition of "Sundials" shows the sundial without the ivy. The dial sits on an ornate stone pillar resting on a two-step octagonal base.
South Hadley Massachusetts USA Horizontal Dial 177
ca 18 inch diameter horizontal dial. Roman numerals, 5 AM to 7 PM. Zodiac signs in circle within numerals. Capricorn and Sagittarius misplaced. Gnomon replaced, 1991. Dial sits atop a two-step octagonal base, ornate carved pillar.
South Lee Massachusetts USA Vertical Dial 838
On the transom of a brown wood shingled and stone building that looks like it once was a church is a vertical south declining wooden sundial about 2 x 2 feet square. The sundial is painted red with a nicely cut wood gnomon. Hour lines and Roman numerals from VI to VI are chiseled into the wood, along with an inscription. The dial is framed in wood as well but the contrasting grey paint is flaking off.
