I gave the question and tree cross-cut image to Grok. It fed the tree image into a series of image processing tools.

Grok:
Counting the growth rings in this tree cross-section image requires analyzing the concentric bands, where each complete ring (typically a lighter earlywood and darker latewood layer) generally represents one year of growth. Using image processing techniques to average the intensity radially from the center and detect the dark boundaries, I count 19 distinct rings.
Therefore, this tree is approximately 19 years old. Note that this is an estimate—factors like environmental conditions can sometimes lead to false rings or missing ones, but this appears to be a straightforward case based on the visible pattern.
Matt: 19 Rings, what an AI-brain-fart. I am impressed that it took on the task. Just guessing by counting rough groups of 10 rings, I see 80 to 90 rings.
