A beam of light illuminates the backstone of Carin T

Autumn Equinox - September 2002

Tim O'Brien in his book Light Years Ago states "It would appear that the construction of Cairn T was specifically designed to cleverly fashion a beam of light from the rising and early risen sun around the time of the equinoxes to define the four year equinox or leap year cycle."
