I did Prometheus II in Peconic. Again stone and steel chain, but no steel pins this time, just a continuous length of chain joined with a shackle. A very strange hollow rock hauled off the beach years before makes it a bird bath.
Prometheus III was placed with the help of Jon Bohl and his 20 ton Hitachi excavator (the man is an artist). Louise suggested that it should include a stone suppended by chain, so I prepared a Long Island beach rock and when we snowshoed into the mountain, I installed the binding chain and suspended rock. By then we were preparing for the war with Iraq.
