I suspect the holes are abandoned oil wells from long ago. Nothing left
but the damage from bringing up the "substrate" to the surface.
Limestone, oil soaked earth etc that no plant can grow in or at least is
favorable to the local vegetation.

That whole area around Galveston is riddled with those holes. I
understand years ago that area had hundreds of oil wells in a few block
area.

Thats my guess!

I stumbled across this earlier today. Below is the quote and link to
picture.

Although I've seen several areas with similar holes, this particular
set is right next to Bastrop Bayou, near the bridge where CR 227
crosses over it. Approximate lat/long is N29.094 W95.290.

Usually the holes are near a body of water: a river, stream, bayou,
canal, etc. And they are always water filled.

Any ideas?
