Berkeley California USA Horizontal 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 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 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 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. Dial shows wear and abuse, with graffiti covering the lower portion of the gnomon. Still, it is awe inspiring.
 
 
San Francisco California USA Stone Sculpture Dial 418
This is a 16 ton granite statue by Richard O'Hanlon entitled "Sunstone I" and was designed in collaboration with astronomer David Cudaback. A small wall of rock with a round inlay of dark stone is supported high upon two tall vertical slabs of granite. At the back is a "heel stone" with marks to show where the sunlight strikes at the Equinox and Solstice.
 
 
San Francisco California USA Horizontal Dial 417
A plain but nicely done brass horizontal dial about 2 feet in diameter mounted on a simple concrete pedestal. The dial is in good condition, but about 50 degrees out of alignment.
 
 
Manchester Vermont USA Vertical Dial 416
A beautiful vertical declining dial, done in white lines and numerals on the side of a red barn. Made of metal and wood, the overall height is about 15 feet. The dial has a clean, modern design using tapered hour lines and simple gnomon. The Arabic numerals for each hour are graded in size to match the size of their hour line, with the largest at noon and the smallest at 8am and 5pm. The Manchester Journal reported that "the sun clock was installed the day before Thanksgiving 1999, with final adjustments being done just as the sun went down."
 
 
Lincoln Nebraska USA Equatorial Dial 415
The Carroll Moore Memorial Dial is an equatorial disk dial built by Cold Spring Granite Co. The granite base weighs 6,270 lbs. and is about 6 ft. in diameter. The granite dial plate weighs 3,420 lbs. and is 5 ft. 8 in. in diameter. The stainless steel 5 inch gnomon rod weighs 200 lbs and is approximately 6 feet long from end to end through the equatorial disk. The dial face has hour marks for all 24 hour hours, placed for symmetrical effect rather than for practical time telling. The hours are rotated slightly to account for longitude so that 12:30 is the nearly vertical hour line. Web site has pictures of dial construction.
 
 
Toronto Ontario Canada Equatorial Dial 414
An equatorial dial with rod gnomon bent into a half analemma. Raised Roman numerals along the equatorial arc from V in morning to VII at night. Gnomon held by semi-circular arc with pleasing proportions that match the equatorial arc.

Suffern New York USA Equatorial and Horizontal Dial 411
Robert Adzema has designed a 10-foot tall, 12-foot long combination equatorial and horizontal dial made out of stainless steel. The equatorial dial has a wide arc showing hours from 6am to 6pm. At the noon hour is a 31-inch analemma illuminated by a 1/4-inch nodus in a rod gnomon. The pedestal holding the dial and rod is designed as the gnomon for an even larger horizontal ground level dial that surrounds the equatorial dial. For this horizontal dial, the hour lines are made of half-inch stainless steel bars are embedded in concrete. An inscription tells how to tell the time.

Macedon New York USA Henge Dial 408
A cornfield maze for the summer of 2000 at Long Acre Farms. Theme called "Lost in Time" features a number of sundials. The 400 x 500 foot cornfield maze, called the "largest living sundial", is in the form of a smiling sun with 12 corn hedge "rays" from 8 am to 6 pm that align in azimuth to the hour and half hour for Labor Day, 2000. Within each hedge is a vertical pole holding an "Eye of Kala" (an annulus) 12 feet above the ground that casts a spot of light across a hedge clearing at the appointed time to a sign at ground level. At the center of the maze is a horizontal dial with a 12-foot gnomon. This gnomon forms part of the smiling sun's nose when seen from the air. Just outside the corn hinge is an analemmatic sundial for visitors to tell time before going through the hinge. In the hinge, visitors are given a small altitude card dial that tells Eastern Daylight Time from June - Oct. Admission fee.
 
 
Starr's Point Nova Scotia Canada Horizontal Dial 407
A small horizontal dial, 8-inches in diameter. The dial is a fiberglass reproduction with metal gnomon upon a cement pedestal. The original dial dates from the 1820s and judging from the reproduction, is in very poor condition. Has Roman numerals, but the hour lines do not agree with the gnomon position. Very difficult to read. North edge of gnomon is cut to resemble a face in profile, possibly in reference to the inscription. On the grounds of the Charles Ramage Prescott House, built 1814 - 1816. Prescott was a merchant and horticulturalist.
 
 
Windsor Nova Scotia Canada Horizontal Dial 406
