The Rock ‘Wall’ in Rockwall, Texas: Prehistoric Man, Extra-Terrestrial, or Natural Phenomenon?

By  | 

If, like us, you simply went about your life referring to Rockwall, Texas, and never really contemplating why it was called that, you’re in luck! We’ve got the answer. The city of Rockwall has, sitting beneath it, a row of hard mineral stones which appear to be stacked, long and narrow, forming what gives the impression of a “rock wall.” Sparking debate for over 160 years, the formation astounds the imagination and has engaged scientific experts on how and by whom this “rock wall” of Rockwall was built.

The question in the back of most peoples’ minds has been whether the wall was built by prehistoric man, or whether it was a naturally occurring phenomenon. The formation has been well documented in at least 11 different locations surrounding and below the city of Rockwall. And beginning in 1852, various excavations have taken place which are mapped and archived by the Rockwall County Historical Foundation. Appearing as random markings on their diagram, these portions of the “wall” began to look like dots or dashes, and markings that may have formed a pattern, or they could simply have been an actual expanse of wall, not meaning anything. But to this day, the entire length of “wall” remains to be excavated.

In large part, the wall has been stumbled upon by accident. When someone was digging a well or plowing a field, a portion would become exposed. Some have actually gone looking for it, having purposely excavated it to study. Dr. Robert T. Hill had concluded as far back as 1901 that the “wall” was, in fact, no more than a naturally formed sandstone dike. Tests that have been run on the rocks since have tried to establish dating and makeup, and have also concluded the very same. Geologists from the University of Texas at Dallas have studied the formation and agree with these findings which, according to the Colorado Geological Survey, confirm that the formations came about from the deposit of sedimentary material which, over millions of years, dried and hardened. This material can often break as it condenses, which forms various patterns. The process has been documented around the world, but what’s unique about this formation in Rockwall is that the sandstone fractured in a way that appears to be in the shape of bricks which were put together symmetrically.
