It has been reported that the engraved compass at the entrance of the sculpture does not point North as expected.  A small, nearby lodestone symbolicly attracts the compass needle in a south-southwestern direction. > Observation: Petrified Tree Elonka's: Kryptos - The Bird's Eye View http://www.elonka.com/kryptos/KryptosAerial.html
