The
light is shown here shining down the passage on 2 December 1997,
and illuminating the back wall. Hitherto no photographic
evidence had been produced for this effect so long before the
solstice. This was the first physical evidence for the prolonged
illumination of the chamber. In early November the sun first
starts to get far enough south to start to shine into the passage,
and by late in the month it finally is low enough and far enough
south to shine onto the back wall itself

By
mid-December the beam of light hitting the back wall has grown
to beas tall as the blocking stone. Starting as a narrow
shaft, it gradually grows as the sun sets, until it is a wide
patch reaching to the blocking stone. We claim the record
for first using a computer to send winter solstice pictures live
from a chambered cairn! Surprisingly it never gets really
very cold in Maeshowe, which was just as well.
