A mysterious 18-mile wall lies beneath a town in Texas which received its name, Rockwall, once residents became aware of the enormous formation they were building upon.
Although many in Rockwall, Texas today are unaware of the origin of their town’s name, older residents will recall times when their family or family friends struggled with the immense wall running beneath their town while trying to dig a well or establish a structure. Some residents talk about the archways or windows their parents found while digging around it, others talk about the nuisance that this giant wall, which altogether forms a large rectangle, presented when they were trying to originally create their homes.
The wall was originally discovered in 1852 by T.U. Wade, B.F. Boydston, and a Mr. Stevenson. They came across the feature while establishing the area, and though they were originally torn on what to call their new settlement, they were so impressed by the wall that they unanimously decided to name their new town Rockwall. Since then, the wall has played a significant part in the lives of individuals settling the area. Excavations into it and the chambers and passageways that it connects to beneath the town have together helped to show that the overall rectangular form of the wall is 5.6 miles long and 3.5 miles wide.
The granddaughter of T.U. Wade, Mary Pattie Gibson, who founded the Rockwall County Historical Foundation, has detailed many excavations into the passages and chambers connected to the wall. The passages generally lead towards the hill which the town is based upon and the wall itself travels around. They’re said to be made with steep slopes in way that’s similar to the passageways that have been attributed to the Mayans further south. Rooms and cubicles are also said to connect to these passageways.
A particular excavation into one of the underground passages in 1909 was led by two men who were pursuing a treasure that local Native American lore placed somewhere in the ancient maze of buried passageways. Apparently, oral tradition passed down by the natives in the region had kept them aware of the now buried complex. Still, no exact area was given to the men, and the effort was eventually abandoned due to the immense size and extreme depth that needed to be searched—roughly twenty square miles—as well as the fact that many of the passages required intensive labor to stabilize.
For Harvard-trained architect John Lindsey, a man who’s spent a tremendous amount of time researching the wall, he’s come to believe the site demands further attention as it showcases what appear to be a variety of man-made features.
“After compiling past records, data, and documents, including recent studies and research, evidence of a prehistoric structure built by man is mounting,” John Lindsey in 1996.
Geologist James Shelton is another figure who’s intensively studied the area and joined researchers like John Lindsey in calling for a greater degree of attention to be given to the structure. He went as far as to publish a paper titled, “An Unsolicited Plea for Assistance in Reevaluation of the Rockwall Co., Texas – Rockwall Anomaly”, where, among other things, he discussed how the geological explanation for the wall being a natural formation has a severe number of issues undermining it.
In one such example, he explains that, “The Rockwall dike system has long been known for its resemblance to construction as opposed to most sand dikes that do not display staggered joint stone masonry features.” As well, he details how, “Various linteled portals and archways complete with arch guiding springer stones have been documented along the wall.” Mr Shelton goes on to say:
“Many of the openings are in fact square and resemble windows or conduits for water. One lintel that was excavated and brought up from a water well in 1949 had what appeared to be an ancient script on it that is roughly in a straight line across the stone. What is more interesting is that a copper coin-like object … found in cuttings from an augered water well in 1870 in Illinois at a depth of 125 feet had two humans portrayed on it and the exact same script etched around the edge of the object.”
Other researchers have dismissed the wall as a natural occurrence, claiming that it must be a very exotic example of a sand dike formation. While most of these researchers will agree that it’s like nothing they’ve ever seen before, the major stumbling block seems to be that the alternative explanation—being that the wall was constructed—is too far beyond their belief system; an issue which prevents many researchers from accepting extremely ancient constructions. The conventional understanding of history says that no civilization capable of creating such a work existed in the area, so acknowledging the wall as artificial means standing against the tenacious mainstream academic community and can amount to career suicide.
“The exposed wall is quite spectacular to see first hand and determining its origin, genesis and age invokes a number of exciting research opportunities that can certainly advance our understanding of this type of phenomena…The most important fact, however, is the point that geologists actually do not know the precise processes that created this feature; and, therefore, a systematic and detailed study of a section of the wall has the potential to expand our knowledge and reveal new data not considered heretofore,” Randall Moir Ph.D Archaeologist.
In 2013, geologist Scott Wolter and Dr. John Geissman—who’s probably the most vocal critic speaking against the idea that the wall was constructed—analyzed the site as part of a History channel special. While they agreed that it was very unique, they decided that it was still possible that it could have been formed by natural means. What they used to prop up this belief was the finding that some of the rocks shared a similar magnetism, which could suggest they were made in the same place.
Yet, this is a somewhat troublesome way to dismiss this site as a natural formation. For one thing, if it is indeed an artificial construction, then it was almost certainly created at an extremely remote time in the past. Right away, that extreme age poses an issue for understanding the origins of the site based on magnetism because natural factors can alter the magnetism of an object over time. For another, the material tested could have come from the same area and is likely to have.
Another aspect to consider is that the mechanism in which the stones were created may be a form of artificial concretion. In other words, the stones were cast in place at the site using a mixture of materials. And if that’s the case, then the blocks would share a similar magnetism. Many researchers studying some of the oldest megalithic sites have begun to consider concretion as a possibility because it explains many of the abnormalities that can be found as a mixture of material can be used to make unique shapes that are more resilient through the ages than square blocks and the issue of transportation and placement also becomes far more practical.
The formations of the wall resemble similar features that can be found further south, in ruins attributed to the Maya, and as far south as Peru amongst the incredibly mysterious ruins of Sacsayhuaman
