aLaboratory of Tree-Ring Research date symbols:
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.

bLocated in southeastern Utah.
