A modernistic steel equatorial on a rectangular steel pillar. The gnomon rod shadow falls on an equatorial ring about 4-inches wide, showing time from V to VII, marked in hours and half hours. According to the Hannibal Courier-Post, "The sundial Scott Haycraft built 14 years ago is now back in its location at Glascock's Landing on the Hannibal riverfront...Haycraft built the 200-pound sundial with stainless steel. 'I wanted to make something that was functional art...' " |

In the middle of the Girard green in a large central plaza is an impressive stone dais with a square pillar rising several feet. On top is a 12-inch square dial with a smooth green patina. The dial has a wide gnomon offset to point to true north. The most striking thing is the Roman numerals that seem "upside down" from most horizontal dials. The reason is that most observers approach the dial from the north, making the dial easier to read. |

An ordinary mass-produced horizontal dial mounted on a simply decorated cast concrete pedestal. 11.5" diameter, cast iron with verdigris finish. The dial face is inclined but in the wrong direction, opposite to what is needed to properly align the style to the polar axis (cannot be corrected because fixture is damaged). Appears to be a Model #2550 'Father Time' dial from Rome Industries. |

This is a standard, but lovely, brass sundial 8 inches in diameter. Chapter ring has hour marks from VI to VI, with short hour lines extending inward from the ring. The gnomon has the traditional silhouette of a bird beneath the gnomon style. An hour glass centered in wings is below the foot of the gnomon. The Headstones of August and Mary Ruge have a marble pillar (12 x 12 x 24 inches) between them, and the dial is on the top of that pillar. |

This is a colorful dial raised on a dais so that traffic doesn't hit it. Called "Light Time", the center of the dial has an artful yellow-orange impression of a sun surrounded by planets, moons and even a comet. Hours are marked in two colors for standard and savings time. The gnomon is 3/8 inch steel in the silhouette of a light house beneath the style line acting as a beam of light. |

This elegant brass horizontal dial was custom made for this site, as evidenced by the word GARDENCOURT and the site’s latitude 38° 15’ cast into the plate at the bottom. The dial is 13.75 inches in diameter, with a design of a series of concentric rings. The innermost ring has 17 lines radiating out from the foot of the gnomon toward the Roman numerals in the third circle. Each of these lines is connected by a graceful curve at its end to the adjacent line, creating a chestnut leaf motif in the inner circle. The next circle is a chapter ring of Roman hours marked from IV to VIII, embellished at the bottom with a stylized oak-leaf. A thin decorative band surrounds that ring. The outermost band contains the inscription and the name of the estate. The gnomon is a simple wedge, cut at the correct angle for the site. Unfortunately it is bent slight off true north. |

The sundial, or more properly an alignment gap in the shape of a cross, is cut into the south wall of the new mausoleum in Bellefontaine Cemetery and Arboretum The cross shaped gap was cut into a 32,000-pound block of granite located at the top of the second flight of stairs, carefully angled at 27.9 degrees through this two-foot-thick block. Every year, on December 20th at 11:58 am, the sun shines through the cut and projects a cross 4x 8 feet in size on the granite floor located at the bottom of the stairs. The cross illuminates the floor for about 4 minutes, only aligning on December 20th at solar noon. |

This is a monumental horizontal sundial that from the ground simply looks like a giant pole with a slanting beam. High above the ground that beam is actually a segment of a gnomon, casting its shadow on the concrete plaza below. Then, if the eye is discerning, the concrete alternates in light gray and darker gray motif for the hour sections. From space (or Google Earth) the layout of the hour angles is clearly visible, radiating from a point considerably south of the gnomon pole, showing the hours from 9AM to 3PM local solar time. Hour line plaques extend from 10AM to 7PM. |

The Vista Sun Wheel is 63 feet [19.2 m] outside diameter and 197 feet [60 m] in circumference. The Wheel is composed of 28 tons of broken limestone. The central cairn is 11 feet [3.4 m] in diameter and 3 feet [1 m] high. In the center is a post marked by a sandstone block about 30 inches [76 cm] tall. The floor of the Sun Wheel called for another 28 ton of crushed decomposed red granite about 3/4 inch [2 cm] thick. Stone spokes indicate the solstices and equinox. Other stones 30-40 inches [75-100 cm] are set to various alignments outside the ring. A post indicates the setting sun on Groundhog Day, indicating one of the cross quarter days. The layout was made by direct observation, watching the progress of the sun along the horizon to solar standstill then return. 18 months were required to observe, mark and verify positions then setting stone and making the ring. The layout is similar to the Bighorn Wheel in Wyoming. |

Analemmatic sundial 16' x 10' (4.8m x 3m) painted as a full ellipse on the driveway to a house. Shows local solar time. Time corrections to obtain civil time (Equation of Time and longitude offset) are given for the first of each month on the Zodiac Walkway. Sunrise and Sunset sighting points (seasonal or "Bailey" points) are provided for a theoretical horizon, but are not useful as the dial site is within a valley. The perimeter of the ellipse is marked with great circle navigation directions for a selection of historical solar and celestial observatories, especially for North America, but all historically inhabited continents are represented. A QR code is provided for a link to a website with instructions for the dial, reference links on sundials (including NASS), and links for the selected observatories on the perimeter. The 2 degree slope of the driveway was not compensated for in the sundial layout, but the dial is unshaded from roughly 9:00 am to 5:00 pm in the summer. |

Noon Mark or Meridian Dial |
Dial 1036 |
This brass mariner's compass about 12 inches in diameter is mounted on the east side of a concrete pillar. It is known on campus as "The Ptolemy Stone". It functions as a meridian transit with altitude marks every half degree engraved on the upper south quadrant. The alidade has a notch on the upper end and a plate at the lower end, designed for measuring the altitude of the sun using the notch shadow (preventing eye damage of sighting the sun directly). The pillar is just over 3 feet tall with a sloped top. The main slope is that of the site latitude. A steeper "north face" is cut plane to the celestial equator. To make the equator "visible", a ring is mounted to the face. The ring casts no shadow on the equinox and from September to March is in shadow. A similar Ptolemy Stone is at St. John's campus in Santa Fe, NM. |

Since the wall of the house/museum does not face true south, this vertical dial is set atop a plinth mounted midway up the south-west wall. The 2 x 4 foot (61 x 122 cm) dial face appears to be painted white wood ornamented with a gold face of the sun held by two black heraldic lions. The gnomon is a simple rod and the dial is delineated for due south with "Lat 40°" painted on the dial face. However, the building is at 41° latitude. Along the periphery of the dial face painted in black are hours are marked in Roman numerals from VI to VI with lines showing hour lines and shorter lines for the half-hours. Quarter hours are marked with black dots. The sundial was restored within the past ten years. |

This sundial was constructed on the top of a 10-foot round, 75-ton column of reinforced concrete used to anchor aerial tram cables spanning 2200 feet across the Royal Gorge. Construction started in January 1969. The column is tilted away from the cables, so the dial face is inclined about 5 degrees toward the south. Hour lines are labeled with Roman numerals from V to VIII, with 15-minute marks between. The original gnomon -- two steel angles welded together -- was melted and twisted and the painted face of the dial severely damaged by a large wildfire in 2013, which destroyed most of the park. The tram has now been replaced with a gondola ride which doesn't use this anchor. The sundial was restore in 2015 but since has deteriorated. |

A 6 foot wide x 5-foot high burnished stainless steel equatorial sundial. The meridian arc is parabolic shaped and the equatorial arc is slightly more than a gracefully tapered half-circle 5 1/2-feet in diameter. The central elliptical gnomon plate, which swivels to face the sun, has an analemma cutout that casts an accurate civil-time shadow onto the equatorial ring below. The gnomon plate is laser-etched with the analemma, months and 365 days of the year, and marks for the equinoxes and solstices, and instructions. The equatorial timeline is laser-etched with hour and minute marks from 6:30 AM to 6:30 PM. The sundial body rotates and locks in position for either Daylight Saving or Standard Time. The sundial is highly accurate compensating for longitude (the equatorial ring is rotated 5min 24 sec early to measure solar time on the pacific meridian) and equation of time (by reading the east or west edge of the analemma plate gnomon shadow). The sundial often indicates clock time to within seconds and the date to within a portion of the day. A stainless steel base cover encloses the mounting hardware beneath. |

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. |

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. |

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. |

Vertical Dial |
Dial 1003 |
This vertical declining dial is made of painted plywood with a simple white background and black hour lines and Arabic numerals. The gnomon is a brass rod without nodus. The hour lines have been adjusted for the difference between the site's longitude and the 75° W standard-time meridian. The hours are numbered as Eastern Daylight Time (EDT) instead of Standard Time, because in winter the sun is mostly low in the sky and trees in this wooded area block sunlight from reaching the sundial. Of course to obtain correct EDT, the equation of time needs to be added to the dial's time to account for the variable meridian passage of the sun. At most this amounts to -14 minutes (mid-February) or +16 minutes (early November). |

Equatorial Dial |
Dial 1002 |
"About Time" was a 30 foot long, 3000 pound wooden pyramid. This installation projected time using two sundials: a gnomonic vertical sundial that swept its shadow of time out across the desert floor and an equatorial dial located on one faces of the pyramid. A platform at the peak of the pyramid allowed observers to become the gnomonic sundial’s apex and to experience 360 deg views of the landscape. At the end of the installation the piece was burned, a testament to the unidirectional march of entropy and time, underscoring the fleeting nature of the present moment. |

Vertical Dial |
Dial 1001 |
This is a south facing reclining vertical sundial made of stone about one and a half meter square. The dial's concrete mount adjusts the dial to true south even though the carillon tower is not N-S aligned. Hour lines and Roman numbers on the dial go from 7am to 5pm. Monthly declination lines show the date as well as the solstices and equinox. A simple rod gnomon exits a gold ball at the top of the dial. The dial itself is well above eye level and hard to read. The other end of the carillon tower has an Aztec calendar. |

Analemmatic Dial |
Dial 1000 |
During the design of the bridge across the lagoon, the walkway was extended in the center on the north side, creating a niche for a 12 x 6 foot analemmatic dial. The dial is painted bright yellow with hours marked from 5am to 9pm (daylight saving time). The 1pm hour mark is set 8 1/2 minutes past local noon corresponding to its location just east of the Central Time Zone meridian. The walkway is marked with a central line using tic marks for each month and solstices. As of 2019, the paint is well worn. The dial has red circular Bailey marks for observing the direction of sunrise and sunset. Latitude and longitude are painted on the dial as well. At the north side of the dial on bridge railing is a sign explaining how to stand on the dial and use the equation of time chart to get civil time |

Sculpture/Artwork |
Dial 999 |
A sun sculpture called "Solar Path". The large 24 x 35 x 12 feet sculpture made by renowned artist Bill FitzGibbons consists of a blue vertical pole and two low sloping wedges. The vertical column makes a linear shadow that is supposed to show approximate solar time as it passes over evenly spaced inlaid hourly numbers from 8am to 8pm. This is not a functional sundial! The short wedge points to where the sunrises on the summer solstice and the longer wedge form points to where the sunrises on the winter solstice. |
