Enchanted Rock

Enchanted Rock (16710 Ranch Rd 965, Fredericksburg TX) is an enormous pink granite pluton rock formation located in the Llano Uplift approximately 15 miles (24 km) north of Fredericksburg, Texas, USA and 15 miles (24 km) south of Llano, Texas. Enchanted Rock State Natural Area, which includes Enchanted Rock and surrounding land, spans the border between Gillespie County and Llano County, south of the Llano River. Enchanted Rock covers approximately 640 acres (260 ha) and rises approximately 425 feet (130 m) above the surrounding terrain to elevation of 1,825 feet (556 m) above sea level. It is the largest such pink granite monadnock in the United States. Enchanted Rock State Natural Area, a part of the Texas state park system, includes 1,644 acres (665 ha).[1]

Geology

Geological exfoliation at Enchanted Rock State Natural Area

The prominent granite dome is visible for many miles in the surrounding basin of the Llano Uplift. The weathered dome is a monadnock. The rock is actually part of a segmented ridge, the surface expression of a large igneous batholith of middle Precambrian (1,082 ± 6 million years ago)[2] material that intruded into earlier metamorphic schists and gneiss. The intrusive granite of the pluton was exposed by extensive erosion of the surrounding sedimentary rock (which is primarily limestone).

Archaeological evidence indicates human visitation at the rock going back at least 11,000 years.

According to the book [6] The Enchanted Rock published in 1999 by Ira Kennedy [7][8]

These hunter-gatherers had flint-tipped spears, fire, and stories. With these resources, some twelve thousand years ago, the first Texans became the wellspring of Plains Indian culture.On the basis of archaeological evicence human habitation at Enchanted Rock can be traced back at least 10,000 years. Paleo-Indian projectile points, or arrowheads, 11-12,000 years old have been found in the area upstream and downstream from The Rock. The oldest authenticated projectile point found within the present day park is a Plainview type, dating back 10,000 years.

The rock has been the subject of numerous geological surveys and paintings.

Legends and Mysticism

Folklore of local Tonkawa, Apache and Comanche tribes ascribes magical and spiritual powers to the rock (hence the name 'Enchanted Rock'). While attempting to hide from Anglo settlers in the area, the Natives would hide on the top two tiers of the rock, since they were unable to be seen from the ground below. The first European to visit the area was probably Álvar Núñez Cabeza de Vaca in 1536. The Tonkawa, who inhabited the area in the 16th century, believed that ghost fires flickered at the top of the dome. In particular they heard unexplained creaking and groaning, which geologists attribute to the rock's night-time contraction after being heated by the sun during the day. The name "Enchanted Rock" derives from Spanish and Anglo-Texan interpretations of such legends and related folklore; the name "Crying Rock" has also been given to the formation.

The following is on a plaque on Enchanted Rock[9]

Enchanted Rock State Natural Area and Conservation

Park activities include caving,[14] hiking, primitive backpack camping, rock climbing and picnicking. The Summit Trail[15] is the most popular hiking path.

Emphasis is placed on activity safety and ecological preservation. Visitors are asked to keep human incursion at a minimum, not disturbing plants, animals or artifacts.[16]

Texas Parks and Wildlife Department partners with Friends of Enchanted Rock,[17] a volunteer-based nonprofit organization that works for the improvement and preservation of Enchanted Rock State Natural Area. Scheduled Summit Trail tours are the third Saturday of the month starting April, May, September, October, November, and December. Private tours are available for groups at other times.
