Others please chime in if I'm wrong about the fence post. It looks like dirt eroded, or someone did a shitty fencing job.

It's not eroded. Just some people pour way too much concrete. If you're going to fill the entire hole with concrete then you need to angle the top so rain water won't sit on the concrete. This is why you see so many post break right at the concrete during storms. The water sits on the raised part and rots the post. You either pour concrete and leave 4-6 inches and fill with dirt so the water can absorb, or you "pyramid"/angle the concrete up on the post....which is a lot more work.
