| Description: |
- A large polar equatorial dial by Erickson Monuments, known as the "Tippit Sundial" given by John Tippit in memory of his son. The dial is of dark red granite, 6 feet in diameter and 6.375 inches thick. The gnomon shaft is steel, extending from the ground through the dial plate and outward another two feet. 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. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. The hours on the under side of the dial were originally engraved backwards. Two plaques provide the Equation of Time to convert solar time to watch time. The dial rests on a cement work 7 feet high.
