Wyoming

 
Casper Wyoming USA Horizontal Dial Dial 367
The horizontal dial is a bronze circle 13.4 inches in diameter with raised lines and numbers and mounted on an iron plate on a pedestal of green stone. The angle of the gnomon is roughly 20 degrees, and the hour lines are designed for a latitude of about 22 deg, clearly not designed for Casper's latitude of 43 deg N. See "Sightings" in NASS Compendium Vol. 6 No. 4, Dec 1999. Pedestal is of the same green stone as the Planetarium building.
 
 
Laramie Wyoming USA Horizontal Dial Dial 159
An ornate 18 inch brass horizontal dial sits on a massive four-stone block pedestal. The dial has hour lines from 4am to 8pm, with hours in roman numerals. Time is graduated into 5-minute intervals. The 12-noon mark is 3/8 inch wide, allowing for the gnomon which is missing.
 
 
Sheridan Wyoming USA Horizontal Dial Dial 840
This monumental horizontal dial is 15 ft. in diameter sitting on a foundation of poured concrete and rebar. The dial face is etched on 4 large granite slabs from Canada. The gnomon is a 6-inch diameter steel pipe 97inches tall with a welded nodus ball and a triangular sheet beneath the gnomon that has a sun and the school logo (a mountain range) cut into it casting projected images onto the sundial face.
