Sycamore canker

[TreeCo]

Check out this canker on a sycamore limb.

I've had this section of a sycamore limb for 15 years. I once took it to a Penn/Del meeting and almost had to wrestle Dr. Shigo to retain possession! I love that guy.

It's hanging in the rafters out in the shop. Dr. Shigo told me that the rings are annual growth rings laid down in the spring and as the weather got warmer the bacteria died that was causing the damage.....and the cycle was repeated the following year...or at least until I came along.

What a fantastic specimen!! No wonder he put up a fight to try to keep it, now where at your place do you keep this useless bit of wood?

That's huge, sort of reminds me of an artists impression of the underneath of MB's foot when he had his accident.
