aLaboratory of Tree-Ring Research date symbols:
B = bark is present.
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.
