| This monumental size sundial is called "Marking Time: and spreads over an area 100 x 50 feet (30 x 15 m). The gnomon is a 12 foot (3.6 m) tall welded stainless steel structure. The last several feet of the gnomon is a thin metal bar ending in a sharp point. Multiple time markers are arranged in hour lines from 6am to 6pm. These marks have the names of all 95 Tennessee counties and the noon line has only one county, Davidson, in tribute to the state capital in Nashville, Davidson Co. The large concrete base of the gnomon has fossil type imprints on the surface. |

| A 6-1/2 foot tall, 4 foot diameter helical cylinder equatorial dial of self-weathering COR-TEN steel plate. The 2 foot long beveled edges of the two ends of the helix serve as gnomons, casting shadows for standard time and daylight saving time onto the interior surface. Time is indicated by the dominant shadow, top in summer and bottom in winter. Hour marks are shallow bored holes in the interior surface; no numerals are present but the noon mark is indicated by two small adjacent holes. The helical curved edges allow shadows to fall on the interior surface throughout the year as solar declination varies. An adjacent bronze plaque describes the dial and gives an EOT and longitude correction graph. Dial is supported by a curved COR-TEN steel plate allowing some springy motion. |

| A simple horizontal dial with a pipe gnomon in a gravel bed, about 6 feet in diameter. Flush stone hour markers have raised Roman numerals. Unfortunately, several of the hour markers are incorrectly positioned, and moss and weeds partially obscure much of the dial face. Because of the presence of trees all around it, the dial only receives the sun in the middle of the day, and hardly at all in the winter half of the year. A plaque nearby explains that dial was installed to celebrate the opening of Burnaby Lake Park in 1977. |

Dial 930 |
| This substantial and durable 30 inch anodized aluminium equatorial dial is mounted on a concrete plinth with a brass plaque showing the Equation of Time and usage instructions. The gnomon consists of two parallel plates each with a figure-8 analemma cut out. When the figure-8 apertures are rotated toward the sun, the dial illumination is corrected for the equation of time by reading the correct edge of the analemma for the date. If it the gnomon is turned sideways to the sun, the gap between the plates form a slit that produces a narrow beam for reading solar time adjusted to the longitude of the Pacific time zone. The hour scale is marked out at 5 minute intervals. Hours are labeled for Standard Time and for Daylight Saving Time. |

| The Quilt Block Sundial, an 8x8 foot painted wood nearly-south facing vertical dial with a steel gnomon rod. Dial face consists of a bold quilt block pattern and includes Arabic hour numerals for local solar time, EST and EDT. Hour lines are corrected for longitude and EOT correction is provided by the profile of purple hills along the bottom of the dial. The star map at the top of the dial represents the starry sky at the first sunrise over the newly formed Yancy County on December 29, 1833. The dial declines 3deg west of south. A 3 foot thick steel frame locates dial away from wall to clear roof overhang. |

| A 9 inch diameter horizontal dial of Welsh green slate with brass gnomon. Hour lines show DST with longitude correction. Declination lines are shown for solstices and equinoxes. The gnomon includes a NASS logo. The dial sits atop a stone plinth with 12 inch diameter top.
The original Sundial of Hope, sponsored by Child Find of Alberta, was placed in 1993 on an original plinth dating to before WW2. The simple dial installed in 1993 had been vandalized and the gnomon was missing. Roger Bailey designed and built this replacement dial to commemorate the 10th Anniversary of the founding of NASS. The new dial was unveiled during the 2003 NASS Conference Sundial Tour. |

Armillary Sphere |
Dial 953 |
| This large armillary sphere stands about 2m tall and 1.5m wide. The dial is marked by roman numerals etched completely through the equatorial band. Large holes form the hour moment, with smaller holes for the half and quarter hours. The meridian ring also serves as support for the dial. In addition are the arctic and antarctic rings. The design of a slot mechanism allows the equatorial ring to be rotated by 15° for Daylight Saving Time. However there is no plaque for the Equation of Time correction to civil time. |

| A steel and brass equatorial dial 49 inches in diameter. The dial simulates an armillary sphere with two crossed semi-circles in a modernistic sculpture. There is a slot in the gnomon that projects a sun line and corrects for the equation of time; the gnomon is turned over at the solstice. Fine adjustments are required near the solstice to show correct clock time (MST). Dial built as a Canadian Centennial Project.
Now relocated to a mid-level landing on the entrance stairs but not correctly aligned, producing a 48 minute error. |

| A school yard 6 by 4 meter analemmatic dial of pigmented concrete. The Sunclocks registered design has two hour ellipses, the outer one for standard time, the inner one for daylight saving time. The zodiac table is larger for the fall and winter periods so the design is really two sundials in one. Longitude correction is included. The plaque provides instructions in French and English and notes the dial marks the 50th anniversary of Ecole Banff Trail.
The plaque instruction to stand on the current month is misleading; the user should straddle the dial centerline to avoid an offset error. |

| 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. |

Dial 1 |
| A 90 ft. diameter horizontal dial with a large reflecting pool beneath the gnomon designed by architect Joe Wong and solar engineer John Yellott. The dial is constructed using a steel frame and covered in anodized copper. The hour markers are 4 ft. diameter concrete circles. The dial is designed to show solar time corrected for the time zone offset. Thus the hour markers have been moved ahead of the solar time position. The hour lines are separated by alternating dark and light colored stones. The gnomon itself is 4 ft. wide, 72 ft. long and the tip is 35 ft. high. A pilot dial at a scale of 1/4 in. =1ft. is at the South end of the large dial. It is constructed of gold-anodized aluminum with time lines at 10 minute intervals. An equation of time plaque is nearby. The upper surface of the dial formerly served as a solar water heater to provide hot water to the city's first office building. Numerals face outward, so that they are more easily read by viewers. |

Dial 734 |
| A large vertical dial on an east-declining south stucco wall of an elevator tower in the parking lot of McClellan Airport. The gnomon, hour and declination lines and Arabic numerals are stainless steel. The dial design is flawed, incorrect for either a point-in-space nodus dial or a polar-inclined gnomon dial. The installed gnomon is horizontal but if intended to support only a nodus, the location is wrong; the nodus shadow is outside the lower declination line in the photos. The hour lines radiate from the gnomon base as for a polar-inclined gnomon; they should radiate from a point much higher if for a point-in-space nodus. |

Equatorial Dial |
Dial 911 |
| Anthony Vitale, a life-long steel worker and internationally know metal sculptor, designed a dial for the place he once worked: Carnegie Steel. He started with a flat length of steel 72 inches long, selected the distance between hour lines to be 6 inches, delineated in 15 minute intervals. The result was an equatorial half-ring 45.836 inches in diameter. He added 3 1/4 inches buffer on each side of the equatorial, creating an outer ring 52 inches in diameter. Along the meridian half-ring, the sun's declination is marked with months when a nodus cross bar casts a horizontal shadow at solar noon. The concrete base can unfortunately be rotated and it seems to point to the magnetic north, but bringing a compass or modern cell phone near the steel armillary instantly creates a distortion. |
