Get out your scuba gear. You can solve the debate about growth rates and
size of the original white pines once and for all by diving and
retrieving the mast of ships sunk in battles and storms during the
1700s. You'll be able to write a book about it and have your own TV
show too!

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.
