I do not think in the mud puddle theory. There is a moat right to the right where rain would drain. There is also no depression for holding any puddle.

I think there is a depression in the treeline and grass and also slightly on the road. I would say that there has been a broken/bend tree/bush laying in the way for over a year and was recently removed. There is no debre left, as the grass was also cut recently by a machine that also could have picked up any leaves.
