I see checks about 1/4 the way in -- they're a little masked by the chain burns.
They're dark radial lines. They will not appear on the surface of a log in a damp place, because they close up, but cutting through the end shows them.
If cut, as the wood dries it opens them up again, but they're there already, and have been for some time -- which is why they are gray.
Still, most of the log is sound -- if the end is any indication, and the checks may be far enough apart to use the space between them. It would save the most wood to first split the log directly through one of the checks -- easier, too.
