From Wikipedia: The large spherical boulders in Rock City are giant calcite-cemented concretions, typically called "cannonball concretions" because of their shape. They range in diameter from 3 to 6 meters (10 to 20 feet) with the average diameter being 3.6 meters (12 feet). These concretions lie 2 to 8 meters (6.6 to 26 feet) apart. These boulders consist of well-sorted, medium-grained sandstone, which is tightly cemented by calcite. The sandstone consists of more than 95 percent quartz sand. About 20 percent of the original sandstone, mostly feldspar grains, has been replaced by calcite.
Similar formations can be found at Mushroom Rock State Park, about 40 miles away.
I liked the blue inclusions here. A coworker is going to retire soon and is preparing to sell her home. In cleaning out some of her stuff was a box with several rock samples. I took them home.

Like most isolated petroglyph rocks in Georgia, Sprayberry Rock is not in-situ. It was moved a hundred feet or so to accommodate a new bank building, in 1984.
There are three prehistoric feature types on the rock. Only one of these features can be associated with a time period. During the Late-Archaic Period (5,000-3,000 years B.P), steatite or soapstone outcrops were quarried to produce bowls and other vessels. Soapstone bowls were traded all over the eastern and mid-western U.S. In Georgia, the bowls were often carved with tools fashioned from diabase (a very hard volcanic rock from instusive dikes found from Atlanta eastward). There are at least seven soapstone bowl preforms or bowl scars ( where a bowl was actually made and removed) on the rock. One preform was in the later stages of completion when abandoned.
The last two prehistoric features can't necessarily be associated with the Late-Archaic Period. Cupules are a poorly understood feature. In some cases they appear to have a utilitarian purpose and are often referred to as nutting holes. In other cases one to several hundred cupules were placed on isolated rocks or outcrops and appear to have no apparent function. Seldom are they arranged in a recognizable pattern. Cupules that appear to have a utilitarian purpose are often on outcrops near streams. It is thought they were used in the processing of nuts and acorns. This activity probably occurred from the Archaic and well into the Woodland Peroid, and possibly later. In come cases, cupules are considered an art form. There are over a dozen cupules on Sprayberry Rock. Their meaning or use is unknown.
The third type of prehistoric feature on Sprayberry Rock is petroglyphs. This is considered an art from. There are at least three images of concentric circles concentrated on one end of the boulder. There are various interpretations on the meaning of concentric circles. It is impossible to determine at which point these circles are produced. If they are associated with the bowl quarrying they are quite old. Concentric circles appear on other isolated petroglyph rocks in Georgia.
I have never seen an archaeological report on Sprayberry Rock. I have no idea if artifacts were recovered before it was moved. For more information: www.georgiaencyclopedia.org/articles/history-archaeology/...
Union Pacific's Rockford local crosses the Rock River in downtown as he heads west for their small yard. The crew will spot a couple of the steel cars to the west at Liebovich Steel and then take the gondola and the tank car up the KD Line for customers in Loves Park.

The Logan Rock is found on the outcrop of rocks in the middle distance. In the far distance is Lizard point.
The Logan Rock is an example of a logan or rocking stone and is situated on this outcrop of rocks.
Logan Rock is remembered because it was at the center of a famous drama. In April 1824, Lieutenant Hugh Goldsmith, R.N. (nephew of the famous poet Oliver Goldsmith), and ten or twelve of his crew of the cutter HMS Nimble, armed with bars and levers rocked the huge granite boulder until it fell from its cliff-top perch. Goldsmith was apparently motivated to disprove the claim of Dr Borlase, who wrote in Antiquities of Cornwall in 1754 that:
In the parish of S. Levan, there is a promontory called Castle Treryn. This cape consists of three distinct groups of rocks. On the western side of the middle group near the top, lies a very large stone, so evenly, poised that any hand may move it to and fro; but the extremities of its base are at such a distance from each other, and so well secured by their nearness to the stone which it stretches itself upon, that it is morally impossible that any lever, or indeed force, however applied in a mechanical way, can remove it from its present situation.
Goldsmith was determined to demonstrate that nothing was impossible when the courage and skill of British seamen were engaged. The Logan Rock slid aside and was caught in a narrow crevice (it did not fall from the cliff as claimed by some).
This upset the local residents considerably, since Logan Rock had been used to draw tourists to the area. Treen had become a lucrative tourist destination. Sir Richard R. Vyvyan was particularly unhappy. The local residents demanded that the British Admiralty strip Lieutenant Goldsmith of his Royal Navy commission unless he restored the boulder to its previous position at his own expense.
However, Davies Gilbert persuaded the Lords of the Admiralty to lend Lieutenant Goldsmith the required apparatus for replacing the Logan Rock. The Admiralty sent thirteen capstans with blocks and chains from the dock yard at Plymouth, and contributed £25 towards expenses. Gilbert also raised more funds
After months of effort, at 4.20pm on Tuesday, the 2nd of November, 1824, in front of thousands of spectators and with the help of more than sixty men and block and tackle, the Logan Rock was finally repositioned and returned to "rocking condition". Apparently the total final cost of this enterprise was £130 8s 6d. The original receipt for this expenditure can be found today in The Logan Rock public house in Treen. However, it is not clear how much of the remaining £105 Goldsmith had to make up out of his own pocket.

Ayers Rock en de spectaculaire zonsondergang (of zonsopgang). De rots gaat over van warmrood naar donker purper, altijd met een inwendige gloed.
Uluṟu of Ayers Rock is een reusachtige rotsformatie die ongeveer in het midden van Australië ligt, in het Noordelijk Territorium, in een gebied dat wegens de rode kleur van de grond ook bekend staat als het Rode Centrum.
Voor de lokale Aborigines, de Anangu, is Uluṟu een belangrijke religieuze plaats. De rots is verbonden met hun mythologie, de Tjukurpa, ook bekend als Droomtijd. Alle facetten van de rots hebben een bepaalde betekenis en zijn met elkaar verbonden via de mythologie in de Tjukurpa. Bepaalde scheuren in de rots zijn voor de Anangu de overblijfselen van een strijd tussen twee mythologische wezens uit de Droomtijd.
Verschillende kleine gaten worden geassocieerd met holen gegraven door mythologische mollen. Zo vormt de rots als het ware een Bijbel voor de Anangu, die geen schrift hadden om hun mythologie op te schrijven. Er zijn verschillende heilige plekken rondom de rots die een speciale rol spelen bij mannen- of vrouwenrituelen.
Uluru, also referred to as Ayers Rock, is a large sandstone rock formation in the southern part of the Northern Territory, central Australia. It lies 335 km (208 mi) south west of the nearest large town, Alice Springs; 450 km (280 mi) by road. Kata Tjuta and Uluru are the two major features of the Uluru - Kata Tjuta National Park. Uluru is sacred to the Pitjantjatjara and Yankunytjatjara, the Aboriginal people of the area. It has many springs, waterholes, rock caves and ancient paintings. Uluru is listed as a World Heritage Site.

Legend Rock State Petroglyph Site
Legend rock is not a single rock but a 100 foot cliff of Cretaceous Sandstone that rises over the small but flowing Cottonwood Creek on the western side of Wyoming’s Big Horn Basin. The site contains some of the oldest rock art found in North America. Scattered along an area over 800 yards long there are over 300 petroglyphs scattered along its length that archaeologists now believe range in date from about 11,000 years ago to perhaps the mid-19th century. These carved images are carved the desert varnish, a mixture of iron and manganese oxides, on the stone's surface because both stone. Some of the petroglyphs nearly blend into the desert varnish because over the millennia the minerals have also precipitated on them. This patina enables scientists to estimate the date of the carvings. An etched handprint found at the site has been dated at 10,700 years ago, with an error range of plus or minus 1,400 years. Adjacent engravings are dated to about 6,800 years ago.
The art here is defined as being Dinwoody in style which is found only in Wyoming. At the time the Europeans arrived the native peoples in the area were the Shoshone. It is believed that they or their predecessors may have made some of the art at Legend Rock. Traditionally, the Shoshone believe the images were not made by humans but by the spirits they not only represent but embody. In this context, the chipped forms offer vital portals to other realities. Archaeologist Larry Todd said “Much like visiting a cathedral, a visit to Legend Rock is likely to inspire a certain sort of respect and sense of awe, even though you may not be of the particular religion that made it.” (Billings Gazette, Sunday 23, 2010)A National Historic Site since 1973, Legend Rock is only beginning to be deciphered by archaeologists and scientists working with the peoples who have long revered it. Together with many other rock-art locations across the western US, it demonstrates that America has a rich and ancient cultural history. Moreover, Legend Rock is linked by technique and imagery to sites around the world—Twyfelfontein in Namibia, Ningxia in China, and Alta in Norway, to name a few—all made by burgeoning human populations after the glaciers receded and the modern world began to take shape.
