One source was:
https://kidsgardening.org/growing-guide-sugar-maples/
Therein it read:
According to the Champion Trees National Register, the largest known sugar maple in the country is in New London, CT, and measures 123 tall and 86 wide. The trunk has a circumference of 219 thats a diameter of almost 6'"

(Who is the excellent mathematician who did this math? Public Skoolz? Looks like it should be 6.9 in diameter ..... nearly 7 feet.)

Nevertheless, I'd love to see a MAPLE TREE that big!
We have three mature Maples in our house yard and we tap them for syrup in the spring.
They are one of my favorites, too. But those Silver Maples will be the first tree to fall on your house - plus they have all those messy ‘propellers’ to fish out of the gutters.
We never sold them at Jung’s. They grow fast but aren’t worth the trouble they can cause.
You can also tap Box Elder trees for syrup - they’re in that same family, though are basically a scrap tree you want to be rid of, too. ;)
