Description:
  • A steel and brass equatorial dial 49 inches in diameter. The dial simulates an armillary sphere with two crossed semi-circles in a modernistic sculpture. There is a slot in the gnomon that projects a sun line and corrects for the equation of time; the gnomon is turned over at the solstice. Fine adjustments are required near the solstice to show correct clock time (MST). Dial built as a Canadian Centennial Project.
    Now relocated to a mid-level landing on the entrance stairs but not correctly aligned, producing a 48 minute error.
