The four outer stones are oriented to mark the limits of the 18.6 year lunar declination cycle. The center column features a hole through which the North Star can be seen regardless of time, as well as a slot that is aligned with the Sun's solstices and equinoxes. A 7/8" aperture in the capstone allows a ray of sun to pass through at noon each day, shining a beam on the center stone indicating the day of the year.

Famous quotes containing the word features:
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
