Our sundial of the month for December is the The Sundial Bridge at Turtle Bay. The bridge crosses the Sacramento River in the heart of Redding, California. Opened July 4, 2004, the bridge links the north and south campuses of Turtle Bay Exploration Park and serves as a new downtown entrance for Redding’s extensive Sacramento River Trail system.
As the name suggests, the Sundial Bridge is, in fact, a working sundial and is one of the largest in the world. The sundial shadow traces such a large arc that it can record only four hours a day, from 11am – 3pm. It is not accurate in winter because the shadow is too far into the arboretum to be seen. The shadow, when visible, moves about one foot per minute so you can readily see it move.”
