Hours to Sunset |
Dial 919 |
| This bright and colorful vertical dial declines west, showing "Hours to Sunset" (Italian hours). The dial is decorated in the colors of the rainbow, with a band of color for each hour left to sunset. Quarter hours are marked using thin white lines. The dial was commercially printed on 60 x 90 cm (24 x 36 inches) sheet of aluminum-plastic laminated material with a UV-protective coating. In the summer of 2023, the previous gnomon was replaced with a 3D-printed carrot, the tip of which acts as a nodus. The supporting structure is made from red cedar. |

Horizontal Dial |
Dial 920 |
| This is a 25 cm horizontal dial engraved on a 1/4 inch yellow metal plate (probably bronze). It shows local solar time. The hour marks look precise and consistent, but upon closer look are oddly arranged. The dialist attempted to shift the dial hour lines to correct for longitude (3.17 deg west). The AM hour lines are fairly accurate except the earliest hour lines (IV, V) which inconsistently meet the gnomon foot on the wrong side. The PM hour lines seem to mirror the AM lines except that 3 degrees had been added to each, rendering inaccurate time throughout the afternoon. The gnomon is slightly bent, and nearby buildings and trees block the dial at some times of day. The dial is decorated using simple geometric and visually pleasing patterns. Shallow engraving is used for the hour lines (making them a bit difficult to read), labels, and decoration. The gnomon has a bird engraved on each side and sits on a wedge base. The dial sits on a short granite pedestal with a polished top surface, and was commissioned by his parents in memory of Robert Carlyle Howard (born 1953, died 1970). |

Dial 925 |
| A delightful dial in a delightful setting, well worth the modest admission fee. It is an 18 inch patinated bronze disk mounted on an elegant white granite pedestal, with the hours adjusted to the time zone. The face is a finely crafted bas relief delineated in quarter hours, with the hours labeled using Roman numerals. The lower part of the dial shows the Arms of UBC, along with the leaves and flower spikes of a plant. In keeping with the medicinal purpose of a Physic Garden, the sculpted gnomon features a snake (a traditional symbol for a physician) entwined around a poison chalice (a traditional symbol for a pharmacist). A plaque on the pedestal dedicates the dial to Frank Ebenezer Buck, 1876 - 1970, UBC’s first Landscape Architect. The pedestal is from the 1920s, predating the dial, and was used elsewhere in the Botanical Gardens for their now-lost original sundial. |

Analemmatic Dial |
Dial 927 |
| The analemmatic sundial is laid within a 15-foot circle of light red concrete, set in the middle of a large grey concrete concourse on the south side of the school. Hour points are marked by 4-inch bronze disks embedded in the concrete; the declination scale is made of embedded tiles. The scale is red in part and blue in part, denoting the summer and winter periods. Correspondingly, each hour point hour is labeled twice; red for Daylight Saving Time and in blue for Standard Time. The dial incorporates a longitude correction for the time zone, and features Sunrise & Sunset Markers ("Bailey Points"). All labels were hand-painted by students - a deliberate measure intended to require occasional repainting and hence continued student engagement and involvement with the dial over the years. |

Equatorial Dial |
Dial 931 |
| A simple but elegant and well-executed bronze equatorial dial by renowned local sculptor Gerhard Class. It is about 24-inches in diameter and is mounted on a 16 x 16 x 36-inch plinth of nephrite jade, damaged at one corner. The gnomon has a central slit and can be rotated about the polar axis to create a narrow beam of light for precise reading of the sun's position. The dial shows local solar time plus one hour, corresponding to Daylight Saving Time. The dial's construction is technically perfect but, sadly, the dial appears to be misaligned with the gnomon axis pointing 7 deg west of north. |

Dial 932 |
| This was once a very beautiful sundial sitting on a short concrete pedestal. Now it has a missing gnomon and the dial color is uniformly aquamarine except where the coating has been rubbed away to reveal a white substrate. Tapping the dial face makes a dull sound suggesting the dial is not metal and may be hollow. A possible explanation is that the dial could be made of some kind of cast resin or fiberglass and was then spray-painted. The dial face itself is elegantly sculpted into five sectors, showing clusters of flowers, berries and fruits, creating a pronounced 3D effect. Because of this, the hour lines are reduced to short ticks at the edge of the dial face. The dial shows solar hours, marked off using Roman numerals. |

Sculpture/Artwork |
Dial 990 |
| This artwork along Prince Edward street stretches about 1.5 mile (2.4 km). The latitude and longitude are given for the mid point. As public art the installation is know as Solar Patterns I and II. They are a collection of metal banners attached high on street poles and at eye level, an explanation of the pattern in the banner. Each banner consists of a yellow or orange aluminum sheet perforated with round holes representing the sun following a simple curve that is part of the analemma. The third dot from the top of the banner is replaced by an image of the sun as conceived by various artists ranging from school children to iconic images from various cultures to historic representations of the sun from cave paintings. |

The chapter ring is marked out in Roman numerals running from V (am) to IV (pm) on a large semi-circular arc of open metalwork supported by a trellis structure. It is very large, about 40 meters across. The gnomon is a separate structure and is not positioned or oriented correctly. |

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. |

Analemmatic Dial |
Dial 933 |
| This is a standard outdoor analemmatic dial located on a hillside allowing all-day illumination and providing good views of Vernon and the surrounding area. The layout was designed by James Kanester. Rather than acting as a "Human Sundial" this analemmatic uses a movable vertical pole that sits in a slot in the declination scale. A central figure-8 analemma curve provides an indication by date where to place the gnomon in the slotted meridian grove. The declination scale, designed and constructed by Joel Wrinch, is wooden with engraved lettering and analemma. The dial's hour marks are concrete posts, topped by glass mosaics made by local artist Connie Vetter-Johnson. Only whole hours are marked. Dial furniture includes a larger glass mosaic image of a hawk. The dial's major axis is about 22 feet, the declination scale is about 6 feet long, the hour markers are 12 inches in diameter. The hawk mosaic is about 18 inches in diameter. |

The vertical sundial panel measures 28x28 inches and declines 48° west of south, so it only functions in the afternoons. The dial is longitude corrected and indicates Daylight Saving Time when readings are adjusted using the Equation of Time. The gnomon is a 3/4 inch brass ball nodus attached by a non-polar axis rod to the aluminum Sussman window frame. It is the only stained glass sundial in the world that uses frosted colored stained glass to enhance the view of the nodus shadow. It has three seasonal date lines, a solar noon mark, and other marks showing special anniversary dates. It contains the traditional fly, seen on the the lower yellow panel between 1pm and 1:30pm. |

House was built in 1805 and is now open to the public as a museum. Years before this property was opened to the public, a family member brought this dial from Crossbasket Castle in Scotland, the family seat. The lengthy inscription is probably a later addition, since it is unlikely that they would be quoting Whittier in Scotland. The gnomon angle is 39? 30', probably made for the Washington DC location. However, the dial plate has a latitude of about 48? N, certainly not Scotland. What is the true origin of this dial? |
