I scanned it the other way ...

So that rules that explanation out.

There's a gadji on resonancefm with an hour of playing records backwards and he's just playing a Hendrix track - with reversed guitars ...

Sometimes I think that after taking a bunch of difficult photographs I should smash that camera and pour lighter fluid over it ...

I don't think that line's coming from the mound but, rather, an associated stone behind it. I've only seen these optical photographic distortions connected with stones, originally placed.
