Dial face consists of a bold quilt block pattern and includes Arabic hour numerals for local solar time, EST and EDT.

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 3? west of south. A 3 foot thick steel frame locates dial away from wall to clear roof overhang. This Quilt Block is one of over 150 colorful blocks painted on buildings along the Quilt Trails of Western North Carolina.
 
 
Columbus Indiana USA Vertical Dial 675
An approximately 10 x12 foot brick and stainless steel south-facing dial atop a 50 foot tower. This resembles an actual vertical dial but has a horizontal gnomon rather than a polar-pointing gnomon. The hour lines verify against ZW2000 software calculated angles for a due south dial but are non-functional with a horizontal gnomon. Dial face includes hour lines for 6 AM to 2 PM but no numerals. It's more sculpture than sundial.
 
 
Columbus Indiana USA Horizontal Dial 674

Clear Lake Shores Texas USA Equatorial Dial 673

Denver Colorado USA Horizontal Dial 672

Substantial surrounding building clutter blocks the sun for much of the day, rendering the dial without shadow.
 
 
Albuquerque New Mexico USA Horizontal Dial 669
A 36 inch diameter brass and copper horizontal sundial with a gnomon depicting a bird standing and a bird in flight. The bird motif reminds of "The Bird of Time has but a little way to fly--and Lo! the bird is on the Wing" by Omar Khayyam. The gnomon is buttressed for strength and includes a brass ball at the top as a safety feature in light of a nearby middle school.
