Even the models and assumptions handed to us in school, the workplace, and our communities seem to have a false ring.
A dendrochronologist must be able to read micro-rings just two cells wide, false rings embedded in a single annual ring, fuzzy ring boundaries in tropical trees, missing rings, pinched rings that are missing part of their circumference, frost rings formed from freezing temperatures during the growing season, and fire scars that lack telltale charcoal.
Under a microscope dendochronologists can also see clues (like the relative sizes of cells and the colors of cell boundaries) that alert them to missing or false rings.
