Hay Paul,
Yes...makes sense.
Cottonwood Trees ( at least in Nevada) grow along small
watercourses as may be minimal and even slightly below
ground much of the year, and the water may have quite a lot
of minerals. The Trees are understood to contain quite a bit
of these minerals..
I have seen other species of wood, as Teak, whose habits as
a Tree, I do not know about, but whose wood contained many
pockets of hard white material.
...some Trees seems to do this.
