I have seen some discoloration in my yellow cedar and was wondering if it was rot spore starting. Here is one example.

Thanks

Don't think so....most likely related to a knot or other similar.

It's a the bottom of a bark inclusion. If the wood is sound there and isn't sapwood, it's no problem.

The lower log from a cedar. See on the right where the cedar tree's buttresses at the base fold all the way into the heartwood? Your mark is the bottom of one of those.

Here's one in a finished piece. In this case the handle turned from the sapwood of Pacific Madrone:

Here's an example of rot. These look like bark inclusions but are really rotting bullet holes. You can see some of the bullet in the top one where the saw hit it:

Is it really necessary to shoot the tree before you fell it?

Well done. I can't top that one. ;)

Other than a possible rot pocket, the soft lead bullets are no problem in that even the jacketed ones usually don't hurt sawteeth. But one should excavate anyway, because what will damage the sawblade is the nail in the center of them that held up the target. ;)

Thanks guys for your input.

I was able to cut around the spot anyway.
I am building a 15 ft faering and about to start planking.

I will post a few pics as it comes along.
