San Francisco California USA Horizontal Dial Dial 82
Built in 1913 as a promotion for a housing development that was once a racetrack, this dial boasted (incorrectly) that at 34 feet in diameter and a gnomon style 28 feet in length, it was the largest dial in the United States. Nevertheless it gathered much publicity and newspaper articles thanks to the Urban Realty Improvement Co. The company put out a brochure "The Sundial at Ingleside Terrace with Comments on Homes" using the sundial as a lure to attract home buyers to the newly constructed residential neighborhood. On Oct 10, the same day the Panama Canal was opened, a festive gala was held at the sundial dedication attended by more than 1500 people. Photos show young girls dancing around a small pool that surrounded the gnomon. A light (visible in several early photos) dangled from the tip of the gnomon. Bronze statues of seals were originally in the pool, but by 1920 the pool was filled with concrete and the seals were gone. Today the pool area is painted green.
 
 
Aurora Colorado USA Equatorial Dial Dial 81
A large Erickson Monument equatorial polar dial 6 feet in diameter made of light granite with a 3 inch steel rod as gnomon.

Los Angeles California USA Equatorial Dial Dial 77
A bronze equatorial ring dial with taut wire gnomon on concrete pedestal. Ring is inscribed with hour, ten-minute and minute lines. Plaque states the dial indicates correct watch time so observatory staff periodically rotates clamped ring to correct for EOT, longitude and DST. Dial is located adjacent to the Astronomers Monument atop which is a large bronze armillary. The monument recognizes Hipparchus, Copernicus, Galileo, Kepler, Newton and Hershel. The sundial was originally built into the base of the Astronomers Monument but was relocated a few feet to the south during the 2002-2006 remodeling to allow visitors to more closely approach the dial. The dial sits atop a concrete pedestal.
 
 
Death Valley California USA Vertical Dial Dial 76
Prospector and con man Walter Scott convinced Chicago millionaire Albert Johnson to invest in his gold mine in the Death Valley area. The mine was a fraud, but Johnson began building his Spanish Revival Villa in 1922 that continued until the stock market crash of 1929.

Seattle Washington USA Analemmatic Dial Dial 74
27 foot circle containing a fanciful analemmatic dial made of bronze and concrete with countless embedded items. Seattle Sundial Trails notes "It requires more than a casual look to recognize the paving that tops Kite Hill as a sundial. At first glance, it seems as if the high tide washed over a bed of fresh concrete, leaving lots of marine creatures and wave prints behind.....The structure is colored concrete, with many interesting inlaid objects scattered throughout, including a bronze bear claw, a ceramic crab, pieces of pottery and glass and shells, etc. Many features are in bronze (such as some hour numerals and the [zodiac walkway] on which one stands.... Bronze casts of three pairs of footprints are those of Greening, the (anonymous) donor of the piece, and the donor’s dog! There are, however, so many inlaid objects and the hour numerals are so stylized that the dial pattern is somewhat obscured." At the center of the dial is a large yin-yang symbol, made from light and dark concrete. Within this is the zodiac walkway to stand for casting the hour's shadow. However normal dates have given way to elongated bronze band loops around a wavy center line using zodiac signs to indicate the months. For example: Equinoxes are indicated by Aries and Libra while the summer solstice is the Tropic of Cancer and winter solstice is Tropic of Capricorn.
 
 
Johnson Vermont USA Horizontal Dial Dial 71
One of Kate Pond's first dials, a winning design for an 18 foot diameter dial that now resides on the University of North Vermont - Johnson green. Concrete, Stainless Steel. On the ground concrete paths mark the N-S and E-W axes. The gnomon is a 3 inch stainless steel pipe 9 feet long attached to a concrete base. The hours are marked with 1 foot diameter Vermont granite stones, and at the cardinal points are larger stone markers. Kenneth Leslie, Assistant Professor of Art, remarked, " I have the idea of a student sitting against the North marker, reading a newspaper for a noon class, and knowing it's time to leave when the shadow crosses his paper."
 
 
Jerico Vermont USA Horizontal Dial Dial 70
50 foot diameter horizontal dial of steel, concrete and stone. Called "Polaris". The gnomon is 10 foot high forming a stone pyramid.

Trois Rivieres Quebec Canada Vertical Dial Dial 66
A declining vertical dial approximately 6 feet wide and 8 feet tall of painted wood. Diol declines 58? west of south. Dial includes a two-lined analemma noon mark that shows noon corrected for EOT. Hour lines with Roman numerals show local time from 10 AM to 7 PM. Dial is located about 30 feet high on a wall, above an alcove with a statue of the Virgin Mary. The gnomon length is correct for the shadow of the tip to fall on the noon mark. Dial furniture includes a lunar crescent and a depiction of a beaver carrying a tree branch, in a classic French tradition and similar to dials of Zarbula's overall design.
 
 
Stanstead Quebec Canada Horizontal Dial Dial 65
A horizontal dial "sculptural triptych" called "Zig-Zag". Three steel pipes 8x15x13 feet define the sundial. The shadow from its highest point will run along the lower horizontal section exactly E-W at the equinoxes. Stainless steel bolts on the horizontal section serve as hour markers to that time is recorded throughout the year, with the first section of the zigzag serving as the gnomon. The dial-sculpture was funded in part by a 1991 award of a Vermont Community Fund Grant. See NASS Compendium Vol. 1 No. 2, May 1994
 
 
Oberlin Ohio USA Sun Alignment Dial 63
When is a flag pole more than a flag pole? When it has cement walkway curved for the summer solstice, a path for the winter solstice and a distinguishing straight cement line for the spring and fall equinox.

Danvers Massachusetts USA Vertical Dial Dial 42
An east- declining vertical wood dial above the main doorway of the Rebecca Nurse House. Rebecca Nurse was a victim of the Salem witch trials in 1692. The House was restored in 1909 and it is believed this dial was added at that time; there is no evidence the house originally had a sundial.
 
 
Boston Massachusetts USA Vertical Dial Dial 41
Once high on east facing wall of the Old State House, was a vertical declining sundial originally built in 1713. The 6x4 foot dial was just above the third story window. It was restored by R.N. Mayall in 1957. But the background became a faded blue and hour lines were hard to see. At least the Roman numerals along edge were clearly visible. In the upper left corner of dial, just above the gnomon,was a small yellow sun.
 
 
Andover Massachusetts USA Armillary Sphere Dial 40
A very large and ornate armillary sphere, approximately 8 feet in diameter. Sculpted by Paul Manship in 1928 and cast by Alexis Rudier Fondeur in Paris. The armillary has large figures inside the sphere at the base and the equatorial circle has signs of the zodiac in raised metalwork. The dial sits atop a well proportioned light granite pillar that is about 3 foot high and 4 foot diameter.
 
 
Dodge City Kansas USA Horizontal Dial Dial 39
Two horizontal dials side by side, one for Central Standard Time and one for Mountain Standard Time. The CST dial shows hour lines for 7 AM to 7 PM, the MST dial shows 6 AM through 6 PM. Corrected for longitude. Each dial is approximately 13 meters in diameter. In front of the dials is a large concrete plaque with the equation of time and analemma. The analemma is represented as summer on top and late months (Feb, Jul) on right. This is not the way it would be viewed in the traditional series of photos nor is it the way a shadow would be traced. The width is exaggerated, presumably to allow a better reading of the minutes of time. The paint is peeling badly.
 
 
Bloomington Indiana USA Horizontal Dial Dial 38
A small horizontal dial, about 18 inches in diameter. The dial plate is tilted 2 deg to the horizon to allow water run-off. However, more unusual is the base that contains a hand crank connected to a scalloped drum that tilts the entire dial to adjust for the Equation of Time. The drum is rotated to the current date and the drum edge pushes a cam that tilts the plane of the horizontal face so that standard time is indicated to within half a minute. The dial is actually mounted on an equatorial axis. Since 1979 the dial has gone into a state of disrepair and is overgrown by bushes.
 
 
Orlando Florida USA Horizontal Dial Dial 37
This plain dial formed on a concrete base has an elegant gnomon, designed with an interior curve and oval. But alas, don't go to Florida to find it. Sometime in 2013 as Harcourt closed its Florida office, the new tenet had no use for the sundial and had it scheduled for demolition.
 
 
Lake Wales Florida USA Vertical Dial Dial 36
Beautiful vertical dial, approx 12x6 foot of Georgia marble with a brass gnomon approx 5 foot long. Declination lines present. Hour & half hour lines with hours in Roman numerals. Sunburst pattern above gnomon. From the Guidebook, published by the Garden: 'The famous sundial carved on the south wall of the Tower indicates the latitude and longitude of Iron Mountain. It is known as an erect declining dial as it stands vertically at an exact right angle with the surface of the earth... and does not face directly south but is tilted towards the east with a declination of 4 degrees, 20 minutes.' It has an Equation of time chart and shows the days of the months as well. Directions are to 'Add minutes shown for each day to obtain Eastern Standard Time.'
 
 
Swarthmore Pennsylvania USA Vertical Dial Dial 35
Modern design for a vertical dial declining 20.5 deg east on a stone block wall. The gnomon is a right-angled sheet of bronze, casting shadows onto granite hour marks from 6am to 4pm. The dial was designed by Marti Cowan using Waugh's formulae for vertical dials. Frederick Orthlieb, professor and chair of the Dept of Engineering at Swarthmore "had a part in locating the bent-plate gnomon so as to give correct indications on the vertical wall. As installed, the gnomon's indicating edge (which lies on a Polar Axis) casts quite a short shadow in Autumn and Winter and requires some observing skill to make a close estimate of indicated time, but in Spring and Summer the longer shadow moves over the granite hour marks very plainly." A double-line mark at 11am indicates noon during Daylight Saving Time. The second mark is slightly askew if one looks carefully.
 
 
Washington District of Columbia USA Horizontal Dial Dial 34
A cathedral landmark. 6 foot rectangular crypt with a 2 foot circular horizontal dial in bronze. Adjoining the dial is a cross noon marker that casts its shadow onto the crypt with major Christian holidays marked through the year. Gnomon has a folded shape of 2 cm width but the hour lines form only one dial center although the space at noon gap is 1 cm.
 
 
Watertown Connecticut USA Vertical Dial Dial 32
Norman Bliss, who reported this dial, taught astronomy at Taft School for many years. He challenged students to find this abstract dial. The dial no longer exists and was destroyed when the building was demolished.
 
 
New Haven Connecticut USA Vertical Dial Dial 30
Vertical dial on Sterling Library. Rectangular stone with hour lines and Arabic numbers. Gnomon is a plain rod emanating from a sunburst. Stonework shows it to be built into the wall of the library.
 
 
Mystic Connecticut USA Armillary Sphere Dial 29
This armillary dial with a sailing ship weather vane is on the cover photo of Albert Waugh's book "Sundials - Their Theory and Construction" (paperback edition). The dial sits atop a short stone platform outside of the Treworgy Planetarium, on the grounds of the Mystic Seaport Museum in Mystic, CT. To correct solar time to clock time, the dial has an Equation of Time table at the base. The armillary sphere underwent a restoration in the summer of 2015, removing corrosion, repainting the dial structure and equatorial band, and re-stencilling the longitude degree markings.
 
 
Hartford Connecticut USA Equatorial Dial Dial 28
A bronze equatorial dial presented to the college as a gift from the class of 1889. For its age, it is in remarkably good condition. The 3 foot wide by 2 foot tall half cylinder is engraved with both hour and declination lines. At the noon-equinox point of the dial face a perpendicular pole rises to the centerline of the cylinder and supports a N-S gnomon rod. Unfortunately the southern portion of the rod is missing. The base is a square, tapered pillar.
 
 
Hartford Connecticut USA Polyhedral Dial Dial 27
This is an 18th century polyhedral dial (dodecahedron). The dial was originally located at The Abbey, Storrington, Sussex, England. Carved stone with ten dials on a dodecahedral, some sunken, some planar. Pillar is about 12 ft. high.
 
 
Cincinnati Ohio USA Armillary Sphere Dial 26
This is an unusual armillary sphere without the standard gnomon rod, allowing the dial to be adjusted easily to tell civil time. As generally expected of an armillary or equatorial sundial, there is an equatorial time ring (16 inches in diameter) with engraved hourly time marks fastened to a meridian ring. But for this dial the equatorial and meridian ring assembly rotates on a polar axis. The dial functions as a Pilkington & Gibbs Heliochronometer: A small hole with lens where the equatorial and meridian rings meet allows a focused spot of sunlight to fall upon the opposite side of the rings where there is a plaque engraved with an analemma and associated monthly and day marks along the curve. This assembly is an analemmic alidade, allowing the user to align the spot of sun to an offset along the analemma curve of date that adjusting the sundial for the equation of time and longitude off time zone meridian. Civil time is read on the equatorial ring from a marker located on a fixed meridian. Knowing the month and approximate day, the dial can be read to the nearest minute.
 
 
Bloomfield Connecticut USA Vertical Dial Dial 25
Vertical dial on an eight ton granite cube, 4 foot on a side. Three vertical dials on east, south and west sides. Gnomons are missing Designed by R. Newton Mayall. A similar CIGNA cube dial is in Los Angeles, Union Square. Both dials owned by CIGNA Insurance Co.
