What Was Here Before Rockwall, Texas?

In 1852, three men digging a well in North Texas hit a flat, coursed stone face running away in both directions. They kept finding it — in fields, in creek cuts, in every new well. Close to 20 miles of it, reportedly 7 stories down. When the county was organized, they named it after the wall. Rockwall. For 170 years, credentialed people have taken turns ruling on what it is. Igneous rock. Sandstone dikes. An ancient city. Natural. Built. Natural again. In 1985 the city went looking for the wall it was named after and couldn't find it. But almost nobody has asked the other question — not who made it, but what covered it. And for that, Texas already has a documented answer on file.
