John McCubbin died on December 2, 1898 in a premature explosion on the White Pass between camp 9 and 10. He is buried in the Gold Rush cemetery and that is all that we know about him.
In doing research about that name, we can tell that he was of Scottish heritage and that there were McCubbins in New Zealand, Ontario Canada, Yukon Canada, Scotland and in the U.S.
