Date symbol explanations (from the Laboratory of Tree-Ring Research, Tucson, Arizona): B Bark is present. r Less than a full section is present, but the outermost ring is continuous around the available circumference. v A subjective judgment that, although there is no direct evidence of the true outside on the sample, the date is within a very few years of being a cutting date. vv There is no way of estimating how far the last ring is from the true outside; many rings may be lost. + One or a few rings may be missing near the outside whose presence or absence cannot be determined, because the series does not extend far enough to provide adequate cross dating. ++ A ring count is necessary beyond a certain point in the series because cross dating ceases.
