Well its very sobering to see when an ancient tree finally fails particularly when it happens suddenly in a storm say. Do you know if any shoots did appear from the root system? It would be a pity if noone had tried to take cuttings from the original tree before that failure. It is often a task eagerly taken on by University or college hort depts, something as Arbs we should encourage them to do, very long lived trees always have some genetic advantage over the hundreds and thousands of related trees that did not survive so long.
Thanks for the article, it was as Newguy said a very impressive tree
