Patorno 1 The Enchanted Rock dome of Central Texas is a remarkable sight to behold, both for its mammoth size and the intriguing rock formations it harbors. Located just north of charming, historical Fredericksburg, the intriguing stretch of land is designated as a State Natural Area. The dome and its surrounding grounds are open to the public for a very affordable fee, and attract countless patrons with various interests, including stargazing, hiking, geocaching, archaeology, and bird watching. According to the Texas Parks & Wildlife website, “more than 250,000 people trek to the park each year,” distinguishing Enchanted Rock as “one of the most visited parks in the state park system.” Naturally, such a distinction begs the question: what …show more content…

Early peoples gravitated towards the pink dome due to its irregular appearance, which proffered the structure for sacred and domestic use. Most estimates date indigenous human habitation of the formation at 12,000 years ago (although some calculations deviate by approximately a millennium). Several native tribes occupied this region; specifically, much of the fanciful mythology associated with Enchanted Rock is ascribed to the Tonkawa Indians, whose haunting tales of apparitions, romance, and enchantments still linger in the annals of local folklore. As is the case for many previously indigenous land holdings, foreign powers soon …show more content…

During my own excursion to this geological phenomenon, I marvelled at the sheer vastness and unorthodox beauty of the formation, which I was severally reminded by the park’s agreeable staff is not classified as a mountain. If not a mountain, though, what is Enchanted Rock? As I was fairly young at the time of my visit and did not raise questions concerning Enchanted Rock’s identity, I only recently uncovered the nature of the dome, when conducting research for this essay. The domes are indeed not mountains, but the visible portion of a massive batholith, a distinctly different formation. As the Texas Parks & Wildlife website notes, “The Enchanted Rock Batholith stretches 62 square miles,” and the great bulk of this formation is hidden deep below the earth’s surface (Texas Parks & Wildlife Foundation). A batholith is a vast underground depository of granite, which in this case-- by means that I will explain momentarily-- triggered the formation of visible mountainesque structures. These structures are termed “exfoliation domes” for their several distinct layers, each of which has a unique composition. As Robert M. Hutchinson elucidates in his reputable article “Structure and Petrology of Enchanted Rock Batholith, Llano and Gillespie Counties, Texas”, this particular formation boasts outer, intermediate, intermediate central, and core zones, all of which possess slightly different mineral makeups under the larger umbrella of
