When Was This Bushfire?

I saw another photo yesterday of the bushfire devastation at Kinglake - the vast expanses of what look like burnt sticks, once a forest. On the weekend, I took these two photos. We don't have many trees like this, but there are a few. Big old gum trees with the insides burned out, that are still growing, one way or another. The bushfire that went through this area (and I'm told it was a bad one) was in 1969!
