In 1936 the state of Texas cast a claim in bronze that its own parks department now declines to vouch for. The plaque, which hangs in the park headquarters at the foot of the dome, says that in the autumn of 1841 Captain John C. Hays was cut off from his ranging company on the summit, surrounded by Comanches, and repulsed the whole band with such heavy losses that they fled. A second 1936 marker about seven miles east-northeast, where Ranch Road 965 ends at State Highway 16, repeats the sentence word for word. The accounts do not agree with each other about when it happened. The Handbook of Texas puts it in the autumn of 1841 and describes a three hour fight. One nineteenth century account says only that the fight happened about 1844 or 1845, and a story whose date moves by three or four years is a story being retold rather than recorded.
Texas Parks and Wildlife's own magazine states the doubt outright, asking whether Hays fended off a band singlehanded or whether the Comanches were simply unwilling to pursue him onto the rock, and the Handbook observes that the tale received official credence when the state commemorated it in 1936.
The granite underneath the argument is 1,082 million years old, dated by the decay of uranium to lead in zircon crystals, and it cooled two to four miles below the surface. The noises that gave the dome its reputation are sheets of granite expanding and contracting against one another as the temperature falls in the evening.
