Dale,
Thanks for the post. You will be able to raise the Rucker Index somewhat when
you catch up with your measurements. This past April, we (You Carl, and I)
measured two taller specimens than in this list.
Crull Island
sugar maple 8.9 111.1+ re-measure from years back
white ash 10.8 131.7 Carl measure to 131, confirmed to 131.7
Allegheny River: Buckaloons-Kibbe's Island
Species CBH Height Status Rucker Index Comments
Sycamore 12.2 148.3 tallest PA 122.34 Baker Island
white ash 10.8 131.7 Crull Island
Silver maple 10 128.9 tallest NE Thompson Island
E. white pine 8.6 124.7 Hemlock Island

If you just include the islands themselves, then the swamp white oak drops out
and is replaced by the
black walnut 7.7 110.3 Thompson Island
And the Rucker Index for the islands in the river goes to 122.27
