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. |

Dial 473 |
| A horizontal dial of striking modern design about 24 inches in diameter. The dial face is granite with milled wedges, leaving hour lines from 6 am to 6 pm. Hours are represented by small round bronze markers. The gnomon is of unusual design. When installed, the gnomon had a vertical glass plate below the style. The dial doubled as a fountain - water flowed from the top of the gnomon down the glass plate. Each of the bronze hour markers also had a small spray of water. The round granite dial is slightly smaller than the octagonal pedestal and base. A small trough between them recovers water from the fountain. |

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." |

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. |

The site is visited quite frequently by school children and is a great educational tool for dialing. |

Time and direction of sunrise and sunset are marked on the equinox and solstice lines. At the base of the gnomon is a 16-point compass rose. On the left side of the dial is a table for telling time by moon shadows. In the center is a copy of the hands from "The Creation" by Michelangelo. |

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.

| An Erickson Monument polar equatorial dial of light granite, approximately 5 feet in diameter and 6 inches thick. The gnomon shaft is steel, 3 inches in diameter, extending from the ground through the dial plate and outward another 18 inches. The base is a simple tier of raised concrete. 24 hours of radiating lines are inscribed on each side of the dial (summer and winter), ending with the hour in Arabic numbers. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 5 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [The description to obtain watch time attributes Bloomington's longitude as 93:18 East instead of West. Further, it tells the user to subtract one hour for daylight savings time.] Nearly identical to the Port Arthur Dial, Texas, but without city names located in various time zones.

The base is a simple tier of raised concrete. 24 hours are inscribed on each side of the dial (summer and winter) as radiating lines with Arabic numbers at the end. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 6 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [An interesting note about the engraving for the Apr-Sep graph: The line originally said "For daylight savings time, subtract one hour", the word "subtract" was filled in and "you add" was inscribed over it.] In the top quadrant of the dial (both obverse and reverse) where the sun's shadow will never cast, are the names of cities in 16 different Time Zones. A beautiful and well-crafted sundial, it makes a fitting Seaman's Memorial. |

| A large, ornate equatorial dial of brass sits outside the physics department building. The dial is approximately 8 feet across. Two pillars with brass balls support the dial plate. Two more pillars with ball support the gnomon wire. To add a flourish, the north most pillar and ball have a spread eagle holding the gnomon wire in its mouth. Unfortunately this beautiful dial is tarnished by age, with the analemmas for each hour barely visible on the dial plate. The gnomon wire, broken sometime in the past, is jury-rigged and tied together in the middle, resulting in a unkempt look to such a fine dial. A dark, round stone base, perhaps made of slate, approximately 8 foot in diameter supports the dial and pillars. The stone sits upon a 10 x 10 foot concrete pad. |
