Bala Cynwyd Pennsylvania USA Vertical Dial Dial 1023
This is a statuary of a saddened maiden leaning over a vertical dial. The hour lines are thick lines radiating from the foot of the gnomon from 5am to 5pm. The maiden's hand lays over the bronze gnomon. In the center of the dial is a compass rose. This may be an 18th century statuary, a cast copy of a dial and statue in London.
 
 
Haverford Pennsylvania USA Vertical Dial Dial 1022
Not too far up the wall of Union Hall is this vertical rectangular dial about 2x3 foot in size. The limestone dial is embedded in the stone block wall. The declining dial has hour lines every half hour from 5am to 6pm, but the gnomon is missing, leaving only a bronze stain on the light stone face. Most disturbing is a magnolia tree planted by the class of 1972 that now totally blocks sunlight from reaching the dial.
 
 
Haverford Pennsylvania USA Vertical Dial Dial 1021
This bronze vertical dial is about 2x3 feet with a splotched green patina. The hour lines and Roman markers go from 5am to 7pm. The tip of the gnomon shadow shows the date among declination lines from solstice to solstice. It is inscribed as an analemmatic dial, but only because at the noon hour is the trace of the analemma. Considering the motto on the dial, this was probably erected as a memorial to those lost in The Great War.
 
 
Haverford Pennsylvania USA Vertical Dial Dial 1020
Vertical dial about 2-foot square high up on the east wing of KINSC. The limestone dial is embedded in the stone block wall. The declining dial has hour lines every half hour from 5am to 4:30pm. The gnomon is in excellent condition and has not left brass stains on the dial face.

During the morning the shadow climbs up the AM side of the cone, at noon it rests directly on the point, and in the afternoon it starts to descend down the PM side of the cone. The Redevelopment Authority budgeted $18,000 for the meridian dial as a public art project.

Athens Ohio USA Horizontal Dial Dial 1009

Surrounding the chapter ring it reads "Ohio University". Father time stands with a scythe at the foot of the gnomon that contains the profile of a bird. On the dial plate Shakespeare's Sonnet 16 is lightly engraved.

Westville Indiana USA Horizontal Dial Dial 1008
This marine brass sundial at first glance is just a beautiful horizontal sundial with Roman hour marks delineated at 1 minute intervals from 5am to 7pm . But look carefully and at the base of the gnomon on the north side is a vertical stile whose shadow graces a stereographic projection of a grid of 5-minute solar time lines vs solar declination at degree intervals spanning +/- 23.5 deg where the summer and winter solstice paths are highlighted by a bead of small solar dots.
 
 
Ventura California USA Horizontal Dial Dial 1007
The central part of the bronze sundial, approximately 12 inches in diameter, has the traditional hour marks and divisions into 15 minute intervals and surrounded by Roman numerals from 5am to 7pm. South of the gnomon is a simple compass rose with four cardinal points. With the dial at ground level the gnomon has led a hard life and is now held to the dial plate with improvised brackets. Surrounding the dial, doubling the size to 24 inches in diameter is an elegantly engraved ring of the twelve figures of the zodiac, each named on the outer ring with the corresponding month on the inner ring.
 
 
Indianapolis Indiana USA Horizontal Dial Dial 1006
Nestled among the trees in a small triangular park is a monumental horizontal sundial with oversized hour marks. The apparent method of reading the Roman hours that are all south of the 6am - 6pm line, is to look at the shadow then gaze across the sundial to read (upside down) the hour. The hours are 6, 9 ,12, 3, and 6. On the north side of the 6am-6pm line are 3 plaques where the normal 9, 12, and 3 hours should be. One is a plaque for Robert McCord who planted and maintained the park during the 60's until his death. Another plaque records that the McCord Park sundial is dedicated to a local police officer, William Whitfield, who was the first African American police officer killed in the line of duty in Indianapolis. His name is engraved on the central part of the large triangular sundial gnomon. Surrounding the base of the sundial are ceramic tiles from Barbara Zech, a local clay artist who fired the tiles created by students from the nearby school. The tiles have the theme of "home" and "community". The park renovations were headed by the group Keep Indianapolis Beautiful.
 
 
Marshfield Massachusetts USA Analemmatic Dial Dial 1005
This beautiful and educational analemmatic sundial is painted on the blue background of a 14x10 foot concrete pad. The ellipse itself has a semi-major axis of 76 inches and a semi-minor axis of 48 inches, particular suited for children. The zodiac walkway is nicely painted in white with clean stenciling of the months. The solstices and equinoxes are marked in large letters and the cardinal points are flagged in red. [Note: a number of vendors will make paper or plastic stencils that with a stiff brush create impressive lettering.] The hour marks are bright yellow suns enumerated in standard time and offset for longitude. The paint is covered with a clear sealer (Duromar DF-5610 “Solventless, Zero VOC, UV Stable Clear Polyaspartic Topcoat”) plus a bit of "shark grit" (Duromar DuroTrac "Invisible Traction Grit") to roughen the surface a bit to give some traction. This is similar to the approach taken by John Carmichael for the dial he designed at the University of Arizona, NASS Registry #825.
 
 
Longport New Jersey USA Sun Alignment Dial 1004
This concrete and bronze dial is really an alignment sculpture, honoring events from Armistice Day (Nov 11, 1918) to Pearl Harbor (Dec 7, 1941). A five-vaned support casts a shadow onto brass medallions on the time and date of the event such as the 11th hour of the 11th day of the 11th month for Armistice (Veterans) Day. Surrounding the dial are five bronze plaques representing the different branches of the U.S. armed forces.
