We've talked about some old things on the podcast, including the state's oldest building and one of the world's oldest rocks. Today's episode is about a journey to visit another Minnesota artifact: the state's oldest known tree. Star Tribune cartographer Jake Steinberg and photographer Anthony Soufflé join host Eric Roper to discuss their winter trip to the Boundary Waters to report on this topic.
