NOTE: Tree-ring dates are from the Laboratory of Tree-Ring Research, Tucson, Arizona. Explanation of suffixes:    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.
