This is a large granite statue by Richard O'hanlon entitled "Sunstone II" and was designed in collaboration with astronomer David Cudaback. A north-south large polished granite slab has the top cut at the latitude of 38 degrees to sight the North Star. A hole in the stone allows east or west viewing, with limiting angles designed to show the extent of maximum planetary and lunar wandering. An east-west stone crosses the north side of the granite slab, allowing light to pass only at noontime onto a heel stone with marks for Equinox and Solstice. Access by admission to the Hall of Science museum
Berkeley California USA Horizontal Dial Dial 422
At the edge of the bay is a round horizontal sundial about 10 feet in diameter with a stark triangular gnomon. Both gnomon and dial base are of hammered concrete. The base rises above the ground by about 2 feet where Arabic numbers encircle the dial to tell the hours. The dial face is not quite level, perhaps to help with water runoff.
San Francisco California USA Vertical Dial Dial 421
Dial is on an outside wall above the entrance to a private residence. The dial was designed by Stan Musilek. The dial back is made out of galvanized steel. Metal rails indicate the hours. Instead of Arabic or Roman numerals, the proper number of steel balls indicate the time of each hour. Overall, the dial is 4 by 6 feet.
San Francisco California USA Horizontal Dial Dial 420
A small 10-inch cast iron dial from England honors Shakespeare in a garden of the same name. The dial is on a small pedestal in the middle of the courtyard walkway and surrounded by trees. Lovely, but many shadows pass over the dial during the day. The dial plate was made for latitude 54 degrees. The gnomon appears to have been cut down to accommodate the 38 degrees for San Francisco. This "hack" method of correcting a sundial does not give correct time.
San Francisco California USA Horizontal Dial Dial 419
Hilltop Park was built by the San Francisco Redevelopment Agency in 1987. The Landscape Architect was Michael Painter and Associates. Here is a giant sundial 70 feet in diameter with a bright yellow painted steel gnomon 78 feet long. The dial has a cement base and was designed to be used as the stage for a surrounding amphitheater.

Dallas Texas USA Horizontal Dial Dial 385
This is large horizontal dial with a 20-foot-long polar gnomon that rises obliquely from the center of a 34-foot-diameter circle. The hour lines are embedded in the terrazzo pavement showing hour marks and quarter hour ticks. Hour labels (standard time 6-7 and daylight-saving time 7-8) are etched into 12-inch diameter stainless steel plates, each tipped toward the dial's center and supported on a 6-inch-high bollard. The tick marks run further, extending from 5:30am to 7:15 standard time. Hour marks and labels are offset for site longitude, making the time correction between solar and civil time no more than +/- 15 minutes, depending on season. The stainless-steel gnomon has a rectangular cross section that tapers from 12 x 4 inches at the base to 4 x 4 inches at the upper end. The center of the gnomon's shadow (not the shadow's edge) indicates the time. The terrazzo circular plaza is slightly beveled (a squat cone) for proper runoff of rain. The cone's apex coincides with the base of the gnomon and is 10 inches higher than the circumference of the 34-foot circle. The layout of time lines takes this radially sloping surface into account. The terrazzo pavement also includes an embedded polar map of the world adjusted in longitude so that the longitude of Dallas with a star at the dial's location in Texas is due south of the gnomon.

St. Mary's City Maryland USA Equatorial Dial Dial 374
Cement half-cylinder acting as an equatorial time ring with an inside radius of about 18 inches and a concrete gnomon 5 inches thick that looks more like a piece of lumber set on edge than a gnomon. There is no nodus such that the gnomon shadow is a straight line on the wide equatorial band. The cylindrical inner face is stainless steel with an engraved grid of quarter hours and months. The hours are marked in Arabic every half hour and at every hour is a graphical curve of the equation of time (EOT). Using the time of month, one reads across from the month mark to the EOT, giving the time offset. All in all, a very clear way of integrating the EOT with the hourly shadow.

The dial sits on a hexagonal pedestal carved with coats-of-arms of families that lived at the plantation, including the Plater, Briscoe and Satterlee families. The dial face has four concentric bands of hour numerals. The outer band reads local time with an inscription that notes local noon is also noon at Boston, Peru and C. Redondo, and midnight at Borneo and Chinese Tartary. The second band shows noon in New Zealand, London and other locations.

Satterlee in 1910 and restored, including his vision of an 18th century garden in which he placed this sundial, received as a gift, in 1925. Admission fee is required. Call 301-373-2280 for hours.
