I am learning so much from this thread.
Sharon I did not know about the marker trees. How fascinating. I now wonder if that is why one of the huge old oak trees on the hills in City Terrace grew like it did. It fascinated me as a child because it was so different from all the other oak trees on the hills. And now that I think about it, it was pointing in the directions of a spring hidden in a gully between two hills.
Vic, I loved reading all that you described in your above posts. My husband loves his wood that he makes his flutes from. The flute he made from this piece of burled Redwood was beautiful to see as a finished flute. Since he only needs small pieces of wood, he gets them from old trees that have to be taken down, storm damaged trees, reclaimed wood, etc.
