Next in line for measurement is the fat Tulip Poplar in West
Roxbury,
then the Silver Maple in the Arnold Arboretum which is listed in
their brochure as 126'. Right now I'm thinking it doesn't clear
100',
will be interesting to find out. I'd be happy to be proved wrong, if
it's 126' that would be fine too.
I think it's a fused multi-trunk tree multi-trunk tree. It has
impressive
girth, here's the lower trunk, beautiful twist:

Then looking up you see the multiple leaders:

I'll measure and report.

Thesed are some
really nice trees. The single stem 18.1 gbh silver is the
most impressive of these trees.
So if yours is
taller, it will be the new height record. Be sure to get a
good girth, and be sure it is a single stem. Silver.s
commonly have multitrunk trees. If it is a multi
consider doing measurements using the suggest Multitrunk
protocol I listed on the website.

James,
The base as you show in your first image looks really good for a
single, however when you look at the other side seen in the overview
photo you can see at least two trunks.
Take photos and measurements. The tallest tip seems to be on the
left hand trunk. A measure of the diameter (perhaps 1/2
circumference) of the trunk would better allow it to be compared to
singles in terms of size.
The Arnold Arboretum looks like a mine of things to measure, For
example there is the tour of the Centenarians. This is a series of
18 trees generally acquired in the 1880's-1890's. It give you a
chance to measure how much the tree has grown since that time -
assuming they were small when first acquired.
There are many exotic species that likely may not have been
documented in MA that you could accurately measure and set the
record for the species.

Andrew,
It is much easier when you can shoot both the top and base in a
single shot. But you can do it in two pieces from two different
places.
First shoot the top and calculate the height. Then shoot to some
distinctive point on the tree and note its height. The difference
between the two is the height of the tree above the distinctive
point. Then find some place where you can see the base and the
distinctive point. Calculate the height above the base to the
distinctive point as if it were the top of the tree. Then add the
height from the first measurement to this second height to get the
total height of the tree.

I had a chance to measure the Arnold Arboretum's centenarian Silver
Maple today. On their web site they describe it as being "over
120
ft." (not 126' which I'd reported incorrectly). I'm
dissatisfied with
my results because of the 11' difference between highest and lowest,
not very credible to be challenging a published measurement. If
there
are ENTS in the Boston area I'd like to host a measuring session to
see what others get. I have a few interesting trees to look at in
other locations so it might be a good field trip.
Arnold Arboretum, Jamaica Plain, MA
Silver Maple, Acer saccharinum
Acquired 1881
DBH: 68"
Measured from 3 different vantage points:
a. 108.26'
b. 98.02'
c. 97.28'

Andrew,
I'm only about an hour south of Boston and I've been a
member of the Arnold Arboretum since I arrived in
Massachusetts in 1999. I'm not sure how much help I'd
be since I'm not good at using the ENTS method at all,
but I really want to learn and it would probably go
faster to work on this together. I've often wanted to
measure the trees of the Arnold Arboretum, since they
know when they were planted and you could get a good
idea of the overall growth of these trees. The Mount
Auburn Cemetery would be another cool place to check
out.
