Here's that "favorite tree" I mentioned somewhere upthread, catching the last ray of sunset by our house tonight. It's about a hundred feet tall, perhaps a bit more, but I never tried to reckon its age until just now.
Looked it up ... the growth factor for white pine in a forest averages 5 years per inch of diameter at chest height. This tree is 95 inches around at that height, so
5*95/3.14 = 151
it's something like 151 years old. A seedling when the Civil War broke out, and the forest it looks down upon now was a rocky farmed field.
The largest conifer east of the Mississippi, these critters can live 2, maybe 4 hundred years. Before the white man came to cut them down, some grew 250 feet tall. Seems cool that this one tree has made it so far.
Not far from here is a road called Mast Way, where they cut white pine to build masts for the sailing ships.
