Morristown New Jersey USA Analemmatic Dial 819
This analemmatic dial is approximately 20 feet wide by 12 feet long, constructed of reinforced, high strength cast-in-place concrete. Showing both Standard and Daylight Savings Time, the dial uses a dual ring of twenty-eight circular hour markers. Each hour marker is a 12 inch diameter precast paver flush with the surrounding landscaping with an aluminum Arabic hour numeral on top.
 
 
Portland Maine USA Horizontal Dial 818
A large 1m (3-foot) bronze sundial is set on a low granite dais at the center of a white granite ellipse. Surrounding the sundial are three white granite benches, the center declaring this as a memorial to Mayor James Baxter. The hour ring gives the hours from V in the morning to VII in the evening The ring is further divided into 15 minute increments. The dial has a large 24-point star and on the south end of the dial face the words "Baxter Boulevard". The artful gnomon is about 1-inch thick. Unfortunately the monument setting is heavily wooded and little sunlight reaches this fine dial.
 
 
New Milford Connecticut USA Armillary Dial 817
This 9-foot stainless steel equatorial is the centerpiece of "Galileo's Garden". The sundial was built and dedicated in memory of Kathleen Fischer, a sixth-grade science teacher who inspired many students to pursue science. The sundial is an open armillary, with an adjustable hour band so that both local solar time and civil time can be read. At the tip of the gnomon is a bronze and brass true-size rendering of Galileo’s first telescope, honoring the 400 years since Galileo explored the heavens. The North American Sundial Society was privileged to donate to this effort.
 
 
Grande Prairie Alberta Canada Horizontal Dial 816
This monumental stainless steel sundial was built as part of the Grande Prairie Millennium Project. The beautiful gnomon is 12m (40-feet) tall and symbolizes the passage of the year 2000 into the 21st century. Behind the visible stainless steel cover of the sundial's gnomon is a one by two foot steel beam. Engineers adopted computer programming techniques to construct and align the 30 centimetre thick gnomon of the Centre 2000 sundial. Specific factors such as the city’s elevation, its latitude and correction longitude mark time with the region’s Mountain Standard and Daylight Savings Time.
 
 
San Diego California USA Equatorial Dial 815
This broad band equatorial dial was dedicated in 1978 to George A. Koester, former Executive Dean of San Diego State University. The approximately 3-foot dial is on a brick pedestal situated on on a small dais. Concentric brick circles complete the large dial plaza.
 
 
Leisure City Florida USA Gnomonic Dial 814
Amid the many coral blocks (oolitic limestone rock) carved by eccentric Edward Leedskalnin (1887-1951) is a huge monolithic sundial. The gnomon is a horizontal L-shaped piece of iron fastened to the north corner of a limestone block about 8 feet high, weighing about 15 short-tons. Below the gnomon, carved into a second block of limestone is a portion of a hemisphere, smoothly filled in with concrete. Drawn on the hemisphere are analemma shaped hour and half-hour lines from 9am to 4pm. You can read the time with an accuracy of about two-minutes.
 
 
Victoria British Columbia Canada Horizontal Dial 813
This brass horizontal sundial was designed and engraved for use in the town of Hope BC by British Royal Engineers in 1860. The circular dial is 8 inches diameter with a triangular gnomon. Time lines are engraved at 15 minute intervals from 4 am to 8 pm. The dial is on display in the museum beside other survey instruments and the red uniform of a Royal Engineers Sergeant.
 
 
Coeur d'Alene Idaho USA Horizontal Dial 812
In 2013 the city of Coeur d'Alene began a $20M renovation of downtown McEuen Park, a 22-acre expanse, to include a large sundial. But shortly after the renovation started, the city commissioners were told the $51,000 that was to be spent on the sundial was instead to be used to install heavier electrical infrastructure for support of major park events. Fortunately by the end of 2013, the City Staff announced that the sundial was added back to the park's plan, made possible by a $50,000 donation from Parkwood Business Properties.
 
 
Elmira New York USA Vertical Dial 811
The white concrete dial face with surrounding dark red Arabic hour numbers is approximately 2 foot tall by 4 foot wide. The hour angles are clean grooves in the concrete. All are easily visible from ground level. Most striking is the steel gnomon painted bright yellow with an ornate central cut-out of a triangle symbolizing the trinity.
 
 
Elmira New York USA Alignment Dial 810
This solar alignment sculpture called the "Sun Triangle" is made of polished 1/8 inch stainless steel. Its leaning, 10 foot tall pedestal gives the mounted triangle a futuristic look of monumental size, where the tip of the triangle towers 34 feet above ground level. The selected triangle angles are described by the dial plaque, making solar alignments at noon on the equinoxes and summer/winter solstices. There are no line markings or hour indicators on the ground. However, the pedestal is bolted to a buried concrete block weighing approximately 16 tons.
 
 
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.
 
 
Dover Massachusetts USA Horizontal Dial 808
The horizontal dial is in the spiral shape of a Nautilus. The dial was originally built in the 1920's and located at Amelia Peabody's Sun House at 145 Powisset Stree in Dover, MA.
 
 
Winterthur Delaware USA Horizontal Dial 807
A bronze horizontal sundial about 18 inches in diameter. The Arabic hour numbers range from 4am to 8pm, with time delineated into half, quarter, and eighth hours. A side photo of the gnomon shows it is set for about 53° and the top-down photo of the dial (corrected for perspective) confirms this. A DuPont purchase in England?
 
 
Winterthur Delaware USA Armillary Dial 806
The 59" armillary is located in the Sundial Garden, designed by Landscape Designer Marian Coffin for Henry Francis DuPont for the family's former tennis court in 1955. It features an antique armillary sundial weighing 70 pounds. It was collected by the DuPont family between 1850-1920.
 
 
Lake Forest Illinois USA Vertical Dial 805
A vertical south-facing dial, simple in design and visible to the shoppers in the U-shaped town square below. The dial face is plane white with Roman hour numbers fastened to a rod bent in an ellipse. No other delineation (such as solstice and equinox lines) is on the dial face. The gnomon is a simple rod held by an "S" shaped support.
 
 
Logan Utah USA Analemmatic Dial 804
Work to design and make the Analemmatic Sundial was done by students of the sixth grade science class and teacher Eric Newell in 2005. The central walkway uses stepping stones sandblasted with the name of the months. John Westenskow's ceramics classes at Mount Logan Middle School made the time stones. Students surveyed and plotted the location of the stones and provided the physical labor to dig holes and pour cement.
 
 
Pennington New Jersey USA Cylindrical Dial 803
This is an adaptation of the dual cylindrical sundial design by Hoffmann Albin of Butgenback, Belgium that provides for two separate dials to be displayed. In this variation, the two dials are separately displayed after being rotated and locked into viewing position every six months on the solstices. Except for two bronze sleeve bearings, all parts are 304 stainless steel that has been glass bead blasted to reduce reflection, machined, welded or laser cut. The analemmal hour lines, equinox and month lines are laser etched into the stainless steel dial plates. The dials and their supporting cradles are 12 gauge with 12" diameters. The post is 1.75" in diameter.
 
 
Round Lake Beach Illinois USA Horizontal Dial 802
This is an octagonal-shaped horizontal dial 240 mm (9.5 inches)across. The photo-etched plate has a central compass rose and delineated with a half hour circle and second circle dividing the time into quarter-hour increments. Roman numerals mark the hours from 6am to 6pm, with an extra hour mark to extend the dial's time-telling from 5am to 7pm. The dial is adjusted for the longitude of the site. Atop the dial face is a sturdy filigree gnomon approximately 5mm wide and 90mm (3.5 inches) high. South of the gnomon is a graphic Equation of Time.
 
 
Mesa Arizona USA Analemmatic Dial 801
This concrete analemmatic dial is set is a larger concrete plaza located in a City park with an overall theme of Sonoran Desert environmental education and nature-based play.
 
 
Magnolia Arkansas USA Analemmatic Dial 800
A 22 by 17 foot analemmatic dial of stained concrete with Arabic hour numerals of polished brass. The dial perimeter and hour numerals are set in a blue decorative polymer "U" arc, appearing as a large mule shoe that represents the university Muleriders mascot symbol. Dial colors represent the royal blue and gold school colors.
