It is clear, at least, that they are artificial, yes? If we can safely rule out Mother Nature, then these tracks become very interesting because they seem unlikely to have anything but a technological explanation, whether manmade or not.
On an initial observation this appears to be the case.
However, the carts about which Darwin wrote during his visit to the Azores had a separate turning mechanism underneath the tray and not a fixed axle, which allowed for easier cornering.
As well, a pair of bullocks would tread the same path as the cart and being heavier, the cart would obliterate these hoofprints with its wheels.
For me, manmade by carts.
