Southernmost Sunset: West Side of Image Stone

Annually, ten days before and ten days after the Winter Solstice (Dec 11th and Dec 31st with additional imaging on three days before and after those dates), the annual southernmost sunset, offset by the dates above, is imaged on the west side of the image stone.  The image is enlarged and brightened by a custom ground glass lens set at the mid-point of the tunnel.
