We had a fire of a few thousand acres around Hoonah a few years ago, maybe around 2005, but it didn't amount to much. Generally speaking, a five-acre fire is "huge" in this part of the world.
Yellow cedar has some good uses, and I'm fairly sure they will continue to reproduce for centuries. Based on evidence, this going up and down has been going on for a very long time...well, at least as long as this era has been here. Which, relative to many parts of the world, isn't very long.
