It looks like they started moldboard plowing at the edge of the field, going round and round until they got to the middle, where they left a dead furrow and dead furrows in each corner.
They tilled the field that way for years. Now, the field has tillage erosion, and traces of the dead furrows remain.
There is probably a berm around the edge of the field too.
