This is all excellent advice, really appreciated. smile

So far it sounds like the best route it to dig down and try to figure out what I'm dealing with.

This morning I took a fence post, placed it into the hole, and drove it ~2ft before I hit solid rock, so right now I'm thinking it might be a rock seam.

Also I think 'Coal country' is further east of me, and I have no other sinkholes on the property.
