Phillippe , your wonderful photos bring back fond memories of afew glorious days spent up on the Schachen in the summer of 1961 . The Alpine Department of the Munich Bot . Garden was then under Wilhelm Schacht. WE too walked up starting at Schloss Elmau , quite easy when one is young and stayed at the Alm ,just opposite the gate to the Garten . and marvelled at the folly of King Ludwig's Jagdschloss .
