The tremendous cross of trees Joaquin built to surround the hilltop pyre, when this was his estate, The Hights, can still be seen by incoming airplanes at Oakland airport, but authorities would not let his body be cremated in it. Park officials have an agreement with the Oakland airport that planes will not fly over the amphitheatre during performances, incidentally.
