Description:
  • This equatorial dial sits on a 61-inch octagonal base that serves as a columbarium. The dial is reminiscent of Erickson Memorial sundials. This granite sundial is 38.5 inches in diameter and 6 inches thick. The 3-inch diameter gnomon is made of hollow galvanized steel pipe with a white powder coating. The engraving on the sundial was done using a rubber stencil and sandblasting with aluminum oxide abrasive. No water jet was used. The center core hole was cut using a diamond segmented coring machine, like a big drill press with an expensive hole saw.

    The dial's hour lines are engraved on both sides for the summer and winter sun. The summer side shows Daylight Saving Time while the lower back winter side shows Standard Time. The time lines are delineated at 15 minute intervals with hours in Arabic numerals. The lines have built-in longitude correction to give time readings closer to civil time.

    Unlike most planar equatorial sundials with thick gnomons, this sundial does not have a noon gap in its hour lines. Instead, it has a "wrap-around" style using the appropriate gnomon edge. It indicates time from the earliest possible sunrise to the latest possible sunset.
