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.
