On an excavator's youtube work channel out of Derby Indiana, called Dirt Pefect, I just heard them say that vehicles repeatedly going through a low area in a filed had "wallered out a ditch."
In rural West Virginia I often heard this term used to mean the unintentional widening of a hole, like a bolt hole, and I may have heard it usd to meana the intentional wiening of a hole.
What I have not heard discussed here (?) is its use to mean the wearing away of threads on a bolt, which I also heard in West Virginia from auto mechanics.

The South has lots of localisms, such as "feature" meaning resemble, i.e. you feature your dad. However TV announcers in Atlanta (and Boston) speak like the rest of the US.
