There’s a couple of instances where I would immediately think a smaller tree is an older tree; trees growing at or just above tree line and trees living in short growing seasons (closely spaced growth rings). Interesting that closely spaced growth rings (more rings per inch) are weaker than wide growth rings due to “spring wood” vs “summer wood”. I’m very intrigued about your comments on “spiral growth” being an indicator of age. I’ve not heard that explanation before.
