The curator of archaeology at a California museum went so far as to speculate that it could be a petrified human body or a lava-filled cavity resulting from mud enveloping the body of a woman. The mystery was resolved four years later when Dr. Earl Russell Bush, official surgeon for the U.S. Engineers, revealed he was the sculptor. He said he had been stationed at the park in the summer of 1917 and had spent 14 days in October carving the figure. He had pledged his staff to secrecy. A trail constructed in 1930 leads to the “Lady of the Woods,” where she sleeps surrounded by trees in view of those who can find her.
