Description:
  • A large Erickson Monument polar equatorial dial of light colored granite, approximately 6 feet in diameter and 6 inches thick. The gnomon shaft is steel, extending from the ground through the dial plate and outward another two feet. 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.
