No other trees on the island - or the area for that matter - display
this condition.

Is this the work of a pine beetle? If yes, what to do? If not, what has
caused this and is there hope?

At 70' it's a pretty old white pine, probably dying of old age. I have
dozens of huge old white pine on my property, some have fallen and are
rotting away right beside younger specimens. White pine can live 300 years
but that would be exceptional, typically they live 125-150 years. Not every
tree dies of sickness.

Agreed. But in this rugged environment few tend to die of old age and it is rare to see a whole tree go entirely brown over the course of one winter. Any other suggestions?
