Thanks, Junglekeeper. There's a lot in this article that's amazing - the effort to find the trees, recognizing when a new one has been found, identifying them.
As a child my family used to boat in an area up the coast call Desolation Sound (now a marine park). Although this area was only accessible by boat there were many attempts at homesteading back in the early 1900's so today you can still find remnants. There was one area in particular - Prideaux Haven - where the cabin was still visible on shore (at least in 1980) but behind this cabin was a small apple orchard surrounded by a picket fence (or what was left of it). I can still remember seeing small apples forming on these gnarled trees. It would be interesting to see if they still exist and what type they are.
