Tucson Arizona USA Vertical Dial 711
An 84x47 inch vertical dial declining 18? east of south on the outside wall of a private residence. Roman hour numerals are on 8 inch square hand-painted ceramic tiles. The gnomon and support are welded wrought iron painted black. A hand painted EOT graph is shown on a matching ceramic tile. This is a historic home designed by southwestern architect Josias Joesler. Homeowner found original architectural drawings showing a gnomonically-flawed sundial that was never installed and contacted John Carmichael to design this accurate new dial.
 
 
Tucson Arizona USA Vertical Dial 456
This is a 10 x 10 foot south vertical wall dial with hour lines painted on the wall that are corrected for longitude. A unique feature of this dial is the time scale can be rotated forward or back slightly to compensate for the Equation of Time. However, because only the hours are marked, precise minute reading is difficult. Welded steel was used to make the time marker ring and gnomon.
 
 
Tucson Arizona USA Horizontal Dial 464
A horizontal sundial 45 x 61 inches with a monofilar brass cable gnomon and tension counterweight. This is the largest horizontal sundial in the US carved on a single piece of stone, taking two years to build. The dial has hour lines from 5am to 8pm, corrected for longitude. Each hour line has an analemma and in the lower right of the dial is a graph of the Equation of Time. A nodus on the wire gnomon indicates date, with declension lines for summer and winter solstice, equinox, and date lines. 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.
