Not sure if this is something the community here has interest in.
A section of the creek bank has fallen away, revealing that all of the soil has been recently deposited (~ last few decades). The garbage inclusion likely spreads for dozens or maybe hundreds of cubic meters of earth. We don't want to disturb the soil to clean this out so we're limited to surface level cleaning.
On the flipside: it's lots of deep fertile topsoil. The fast growing weeds, like lantana, absolutely love it.
More info that I can ramble on about:
