Berryville Virginia USA Horizontal Dial Dial 520
This lovely horizontal dial was originally located in New York City NY on the grounds of the Doubleday & Co. book manufacturing plant. It was subsequently moved to Berryville VA in 1956, and is now part of Berryville Graphics. The sundial stands about 4 feet high and has a brass reproduction of the Gutenberg Bible of Forty Two Lines (originally produced around 1455) and the hour markers are brass plates of twelve printers' marks from the earliest printers.
Farrell Pennsylvania USA Sculpture/Artwork Dial 519
"Rising Rings" is a cast iron band 11 feet high by 17 feet in diameter with a hole that casts a beam of light onto a central ring monument on the equinoxes. The dial was commissioned by Dr. Swraj Paul, a steel mill owner, to honor his daughter Ambika who died in 1968 of leukemia at age four. This monument honors the inspiration her joy of life instilled in her father. At the central of the dial is a cast iron ring that holds a bronze image of her that is illuminated for several days twice a year. On two dates, Ambika's birthday and the anniversary of the mill's re-opening the noon sunlight passes through the circular opening in the larger ring and strikes markers on the inner ring. Miklos Simon created the portrait of Ambika mounted on the smaller ring.
Redding California USA Horizontal Dial Dial 518
When is a bridge not a bridge? When it's almost a sundial. The 217 foot high suspension span called Sundial Bridge wants to be a sundial, and has come very close. The suspension pylon is aligned true north, but unfortunately performs as an inaccurate gnomon with an inclination of 49 deg (for bridge functionality) rather than for the 40.6 deg latitude of the site. The bridge is 700 feet long and weighs 1,600 tons. Funding for the bridge comes from the McConnell Foundation, Redding Redevelopment Agency, Federal Highway Administration, and Turtle Bay Exploration Park
Watkins Glen New York USA Horizontal Dial Dial 517
A simple horizontal dial made of slate with a copper gnomon. Hour lines are brass rods artfully arranged from 6am to 6pm. The hour lines are corrected for longitude.
Montour Falls New York USA Horizontal Dial Dial 516
A beautiful bronze dial approximately 12 inches long in the shape of a shield. Below the gnomon is a rising sun. On first look, the small dial plate appears backward, with AM and PM hours reversed. However, the inclination of the gnomon is about 48 degrees, suggesting that this pedestal mounted dial is really meant to be a south facing vertical dial! The dial sits atop a circular granite pedestal about 2.5 feet in diameter.
Winter Park Florida USA Horizontal Dial Dial 515
A 12-inch diameter horizontal bronze dial set on a simple fluted pedestal. The dial face includes hour lines with half hour and ten minute marks and a central compass rose. The gnomon includes an adjusting screw allowing the gnomon angle to be set to the latitude angle. The dial is located in a small garden area of an elementary school and includes a nearby flagstone bench. The walkway around the dial is of red bricks inscribed with the names of graduating students. Students learned of the death of a 9 year old classmate and through their fundraising efforts helped establish this memorial dial in their schoolyard. A visitor's pass is required from the administration office before viewing.
Brighton Colorado USA Equatorial Dial Dial 514
This equatorial dial is one of the more distinctive Erickson Monument dials. It is octagonal about 4 feet across, made of white granite. It has a supporting stainless steel rod as gnomon. Hours from 4am to 8pm with 15 minute divisions. The hours are not rotated for longitude, placing the 12pm hour directly at nadir. Below the sundial is a plaque containing a graph of the equation of time.
Nantucket Massachusetts USA Compound Dial Dial 513
A combination of horizontal dial and gnomonic projection dial. The dial is about 2 x 3 feet made of DuPont Corian sitting upon a simple wood pedestal. A small horizontal dial about 8 inches in diameter with a triangular brass gnomon tells Daylight Saving Time using Roman numerals. Then a larger gnomonic dial is inscribed on the remaining surface, telling time from the shadow of the tip of the triangular gnomon. The gnomonic dial has hourly analemmas,telling time using Arabic numbers in Standard Time. Both dial lines are offset for the longitude of 70 degrees west. The gnomonic dial has declination lines for each month. A small analemma on the meridian has the letters of the months, indicating how to read the hourly analemmas depending upon the date. The dial is built to be read from the north, so the user's shadow does not interfere.
Waukesha Wisconsin USA Horizontal Dial Dial 512
A large horizontal dial in a circular plaza made of tan concrete and red brick. The concrete gnomon stands about 16 feet tall. No hour lines are drawn on the plaza, but the hours are set in a circular ring at the edge of the plaza.
Littleton Colorado USA Equatorial Dial Dial 511
The Littleton War sundial is an Erickson equatorial polar dial 6 feet in diameter made of light granite with a 3 inch steel rod as gnomon. Time is graduated by hour, half-hour, quarter hours and 5 minute marks over 24 hours. Noon is at the bottom, matching the 105 degree meridian. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. A plaque provides the Equation of Time to convert solar time to watch time. Dial is in a beautiful setting.
Englewood Colorado USA Equatorial Dial Dial 510
The Archie Lynn Chase Sundial is an equatorial polar dial. Unlike other monumental polar dials (designed by Erickson Monument Co), the dial face is more of a rounded square than a circular disk. Hours, half hours, quarter hours and five minute lines mark the time from 4am to 8pm. The hour lines are rotated for the site latitude. A steel gnomon rod about 3 inches in diameter casts the shadow. Has a plaque describing the Equation of Time.
Torre Coahuila Mexico Analemmatic Dial Dial 509
An analemmatic dial with major axis of 18 feet built of many different types of stone from the Torre?n Jard?n area, including white and red marble, travertine, yellow and black flagstone, and limestone. Insets of gray stone hold the hour markers from 5am to 7pm. The finished dial has been set in desert plants, native to the region, including: Candelilla, Gobernadora, Lechuguilla, Sangre de drago, Huevo de toro, Biznaga, Pitaya, Corona de espinas, Nopal rastrero, and Cardenche. These are all protected desert species. The dial has a compass rose and six disk-shaped maps at the east and west sides to show the course of sunrise/sunset across the Mexican Republic on the solstices and equinox.
Toms River New Jersey USA Horizontal Dial Dial 507
A horizontal dial about 22 feet in diameter. The dial base is stone and gravel outlined in shore juniper plants. Treated lumber, now gray through weathering, is used for the both the hour lines and the marking Roman numeral hours. Nicely fashioned with a hub of green junipers in the center surrounding a simple wood gnomon. Builder Richard Perez started off just wanting something a little different?and the sundial emerged in 1992 as the main theme of landscaping.
Burlington Vermont USA Analemmatic Dial Dial 506
A small table top analemmatic dial 31 x 23 inches, made of Rock Sandstone & gold-plated brass. Has sunrise and sunset seasonal markers. Date line divided into weeks.
Claremont California USA Equatorial Dial Dial 505
A 90 inch diameter spherical segment equatorial dial ten feet high of masonry construction with 3D fiberglass analemmic gnomon 40 inches long. Dial terrazzo face has hour, half-hour, quarter-hour and 5-minute marks with Roman hour numerals for PST. The 5-minute marks are one inch apart. Dial face includes analemma graphic with month dates; a plaque describes how to use the analemma graphic to select which side of the gnomon shadow to use to read time. Base perimeter has 12 ceramic plaques with Zodiacal signs. Indicated time is accurate to one minute throughout the winter and to five minutes in summer. This is remarkable because the dial is located just outside a children's playground and children routinely climb on the dial and swing from the gnomon. An animation from digital images showing the gnomon shadow motion over the course of a full year is available. Dedicated as the Ralph B. Larkin Memorial Sundial. Rev. Larkin was a retired missionary who taught science to children for 17 years in Claremont. Dr. Larkin's father was Edgar Lucien Larkin, Director of the Mt. Lowe Observatory above Los Angeles 1900-1924 using a 16-inch Alvan Clark refractor telescope, described by Alvan Clark as, "the finest telescope I ever made." Ralph Larkin often said, "I grew up with a telescope." The Mt. Lowe Observatory was destroyed in a windstorm in 1928 and the Alvan Clark refractor was moved to Ricard Observatory at the University of Santa Clara, California.
Hillsborough New Jersey USA Obelisk or Vertical Gnomon Dial 504
A gnomonic horizontal dial constructed in bright colors on a 20 by 14 foot concrete pad. The gnomon is a vertical steel pipe 1 meter tall with a small nodus at the top. Hour lines are marked within summer and winter solstice and equatorial lines. The dial is marked with both standard and daylight local solar time. The noon line is complemented by its analemma with the months labeled. The sundial is used by Sunnymead School to aid in the science curriculum. The sundial was designed and created by Michael Folsom-Kovarik as an Eagle Scout project. Construction began on July 20, 2002 and ended on June 28, 2003. Michael was approached by Paul Stockman (the Home and School Association's treasurer) with the idea of building a sundial at Sunnymead School. Michael then came up with the design (made to keep the sundial as a useful teaching tool for the entire school day no matter what time of year) and location. After a year and a half from planning to completion, Sunnymead Elementary has a working and accurate sundial!
Wheaton Maryland USA Horizontal Dial Dial 503
A 20 foot diameter horizontal dial in the middle of a brick patio. The gnomon, about 12 inches wide and 8 feet tall, is made of thin wood painted a verdant green and edged with molding.

Around the circumference of the dial are Arabic number placards for each hour from 6am to 6pm. The flowers are changed seasonally for a gardener?s delight, and during the winter when the plants are dormant, the gnomon is removed and the area is used for a winter light show.
Colorado Springs Colorado USA Horizontal Dial Dial 500
An old horizontal dial approx 60 cm diameter. From 1914-1967 was located at Marksheffel Garage, relocated to Monument Valley Park in 1967. The builder may have been van Briggle Pottery, but its history is more complex: The angles of the hour lines are consistent with a latitude of 43.9° (roughly) but the present location is 38.9°. A gnomon (probably not original) was cut for 34° lat, but has now been corrected. Likewise, the whole dial had to be rotated to true north, being off by some 47°. Hour lines have eroded, and those before 6am and after 6pm radiate from the wrong side of the gnomon. The city has spent a considerable amount of money cleaning up the area, removing the shrubs that blocked sunlight and building a nice brick wall with flowerbeds, so the area looks better, but the dial is worse than ever, with vandals bending the gnomon.
Colorado Springs Colorado USA Vertical Dial Dial 499
A vertical dial approximately one meter square, built into the wall of the 1907 Van Briggle Pottery building. This Memorial Pottery building was erected after Artus Van Briggle's death.

In 1994 Colorado College repaired the gnomon and added a metal equation of time plate.
Los Altos California USA Obelisk or Vertical Gnomon Dial 498
A triangular entry canopy 13 feet height by 128 feet wide by 26 feet deep at the Georgina Blach Intermediate School casts a shadow on the front pavement walkway. The pavement is etched with a gnomonic projection to show the hours and seasons. The dial was created by architects Lisa Gelfand and Andrew Davis who did considerable research for the dial. Their design was submitted to the school district for approval. It's a fun sundial and the students and teachers love it.

Washington District of Columbia USA Gnomonic or Projection Dial Dial 491
With a bit of whimsy at the end of each day for over two years, Dr. James Griffith marked the position of a ray of sunlight on a wall that entered from a west window overlooking the Potomac river. The result is an analemma, tracing the sun's position at 4:10 pm E.S.T. throughout the seasons.

Greenfield Massachusetts USA Hours to Sunset Dial 475
A 5 foot diameter pink Canadian granite horizontal hours-until-sunset dial. The 8 inch thick granite slab weighs 2000 pounds and rests on a short recessed pedestal, appearing to float above the grass dome of a memorial garden. Lines for hour periods 2-12 are marked with Arabic numerals. The gnomon is a 3/8 inch brass rod protruding 4 inches above the dial face. The dial face is engraved, "HOURS UNTIL SUNSET" and, "READ TIP OF SHADOW." This sundial does not function in the usual manner that tells time of day. Rather, this dial tells the number of hours from the present time of day to the time of sunset. These are equal-period hours counted down until sunset. Since it shows a time period, rather than time-of-day, the dial accuracy is not affected by season of year, daylight saving time or longitude location within the local time zone. Further, this particular design uses a horizontal dial face, while most hours-until-sunset dials use a vertical face. This dial is dedicated as a memorial to Dr. Pallav Parakh, a much-loved surgeon who was killed in a tragic auto accident while walking in a crosswalk.
Charleston West Virginia USA Equatorial Dial Dial 474
A bronze equatorial sundial, about 4 feet in diameter.

Monticello Virginia USA Globe or Hemispheric Dial 470
A replica of Jefferson's lost dial, which he recounted in 1817, "My dial captivates every body foreign as well as home-bred, as a handsome object & accurate measurer of time." Made according to Jefferson's design, the replica dial is a 10 1/2 inch painted wood sphere with horizontal lines drawn for the equator, Tropics of Cancer and Capricorn. Longitudinal lines are drawn between the two tropics to indicate the hours of the day. A gnomon fixed to the poles swings around the globe until it casts the smallest meridian shadow. The original sphere was made of black locust wood but the replica is mahogany because it is "more durable, stable and easier to find." The base was originally a model of a capital, the top part of a column, that Latrobe had designed for the U.S. Capitol. It was unique, featuring ears of corn in motif. When Jefferson received the base from Latrove, "it looked bald for want of something to crown it" and so Jefferson designed a globe that "might be made to perform the functions of a dial."
Pinawa Manitoba Canada Horizontal Dial Dial 469
The Pinawa Heritage Sundial located in the center of town was constructed as a city wide effort to create pride and focus. The 17.5 foot high horizontal sundial has a gnomon constructed of steel and the 38.5 by 40.5 foot base is constructed of polished granite, rail, and granite stones. The sundial has two sets of time markers. An outer dial ring indicates local apparent time, while an inner dial ring indicates zonal solar time. Forming an integral part of the sundial, 12 icons were designed and constructed, illustrating the history of the region and its people.
Niagara Falls Ontario Canada Armillary Sphere Dial 468
