This tree trunk had been cut a while back. I was interested to see that some fungus was growing on the cut surface of the wood. However, there was clearly something about the outer rings of the wood that provided nutrients to the fungus that the older wood inside did not. The growth was focused on the outer rings only and there was absolutely no fungus on the inner layers. I wonder what the reason for this was. Any suggestions?
We spent a few days in Whistler having a break. The town hosted many of the Winter Olympic events when Vancouver was the host city. There is an Olympic Park in the middle of the town and the Olympic rings are on display. No surprise that everyone is taking a picture of them. I was surprised that they were the only really obvious sign of the Olympics having been here. The weather changed a lot while we were there and the rings looked very different in the different lighting conditions.
