Log-End Defects

Log-end defects are defects that are visible on the log end's cross-section. Sometimes surface defects are also noticed at the end, but log-end defects are often associated with being hidden. Until the log is further examined or cut, the impact that the log-end defect will have on the entire value of the log is undetermined. Many of these end features are somewhat different from other product defects in that they are often admitted to a certain degree in the products, and their degrading effect often is based on concentration rather than presence alone. Here are some examples of log-end defects (click on them to learn more):
