A shadow stick is a vertical pole placed in the ground. Sunlight casts its shadow on to a level surface below (e.g. a sheet of card or just level ground The length and position of the shadow then depends on both the time of year and the time of day. Local noon can be found from the time when the shadow is shortest. At this time the Sun is highest in the sky and crossing the meridian. However, shadow sticks are not good clocks - the azimuth of the Sun's shadow at a given time changes throughout the year with the Sun's declination. http://www.nmm.ac.uk/server/show/nav.3117
