It would seem so. The truth about great white pines of the past
may lie in the records of masts hauled back to England.

Not that I'm suggesting it but it wood seem from earlier reports
that a 170' white pine would make the grade as a mast of the second
order...

Yep, I think it was my screw-up +0.3 as the height of the tulip
in VA. It shrunk to 166.1 feet.

Seems like I've seen that number recently...coincidence, no doubt?

Don,
I am finally getting to a question you previously asked about
the projection of the full height of a tree from a section
starting near the base. If we assume a uniform rate of taper and
we have a section to use to project the full height, the
following formula will do it.
L = diameter of lower (large) end of log
U = diameter of upper (small) end of log
h = length of log
b = length from L to base of tree
T = total projected tree height
T = [ h/(L-U)]U+ h + b
Example.
L = 5
U = 2
h = 100
b = 3
T = [100/(5-2)]2 + 100 + 3 = 169.6 ft
Remember that this formula assumes a uniform rate of taper. If
the tree increases its rate of taper above the log, which would
be true for old growth forms that have a paraboloid form from
about 5 feet up to where the limb structure takes over, then the
rate of taper can change dramatically.
