Blackburn Lake Analemmatic Sunclock

As the Earth makes its yearly journey around the sun so the sun appears to trace its strange and beautiful analemma in our skies. Instructions: Stand within the current month next to the north/south line. Keep as close as possible to the day's date, and your shadow will tell the time. Use the numbers on the rock wall for Eastern Standard Time, and the inner ring of stone numbers for Daylight Saving Time.
