Description:
  • An Erickson Monument polar equatorial dial of light granite, approximately 5 feet in diameter and 6 inches thick. The gnomon shaft is steel, 3 inches in diameter, extending from the ground through the dial plate and outward another 18 inches. The base is a simple tier of raised concrete. 24 hours of radiating lines are inscribed on each side of the dial (summer and winter), ending with the hour in Arabic numbers. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 5 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [The description to obtain watch time attributes Bloomington's longitude as 93:18 East instead of West. Further, it tells the user to subtract one hour for daylight savings time.] Nearly identical to the Port Arthur Dial, Texas, but without city names located in various time zones.
