Digging up (truck) body parts

At first we thought it might be a car bumper

But it kept growing!

We'd levered it up so it was standing up on end, with logs and rocks behind it

And finally dug it all out and pulled it out of the hole!

This is what we think is either the hood of a truck, or the top of the cab of a truck. Either way, it was a lot of metal to dig up!
