That collapse of caves is collapse and breakdown of cave walls and ceilings are continuing aspects of cave development and modification. massive unfractured limestone can easily span a void of over 100m, but thinly bedded, closely jointed, faulted or poorly lithified limestone may collapse into very small passages. collapse is a significant component of cave erosion. as well as simple falls of unsupported rock forming connections between passages, the collapse process exposes more rock surface area for potential dissolution. as rates of collapse are measured on a geological time scale collapse in natural caves offers a negligible threat to explorers, in comparison to the dangers of roof collapse in mines [9].?

La grotte et le karst de Cango (Afrique du Sud), 2000, Martini, J. E. J.
The author describes a small karst area in the extreme south of the African Continent, with special reference to the Cango Cave, which is a major tourist attraction. Compared with the other karsts of Southern Africa, this area is unique. The karst is typically exogenic, with caves forming by stream disappearance into swallow holes, where the thalweg intersects steeply dipping Precambrian limestone. Wet caves are vadose, with only short phreatic segments and exhibit rectilinear, longitudinal sections. Passages are low, but wide with bevelled ceilings, often terraced. This peculiar morphology is typical of the caves developing exactly on the water-table and seems to be controlled by the abundance of sediments introduced from the swallow holes. If one excepts a short active lower level, Cango is a dry cave of the same type than the wet ones. It is practically linear in plan and in profile, with a length of 2.6 km from entrance to end for a total of 5.2 km of passages. The age of the speleogenesis has been estimated as early Pleistocene from the entrance elevation, which is in between the altitude of the actual thalweg and the one of the Post African I erosion surface, which started to be eroded during the Upper Pliocene. This relatively young age is in contrast with a Miocene model, which was accepted by most of the previous authors. Cango is well adorned with speleothems, in particular with outstanding abundant shields, monocrystalline stalagmites and pools coated with calcite crystals. In the first chambers from entrance, the speleothems have been deeply corroded by bat guano, with deposition of hydroxylapatite. Previously this corrosion was attributed to resolution due to several rises of the paleowater-table. The meteorology is discussed, in particular the high carbon dioxide, which indicates that the cave is poorly ventilated and which constitutes a problem for management and conservation.

The impact of Cango Cave on the economy of Oudtshoorn, South Africa, 2002, Craven S. A.


The evolution of cave monitoring since 19th century is described. The advantage of the development of theories was the possibility to obtain comparable results and forecast the evolution of a cave climate before irreversible modifications take place. The most important parameters to be monitored are indicated. In recent years both important technological improvements have been obtained and the relative importance of each parameter has been reviewed. Kartchner Caverns, Arizona, USA, was opened to the public in November 1999. Some preliminary studies have been performed. Arizona Conservation Project, Inc. (ACPI) established 22 monitoring stations. An evaluation of the impact assessment was obtained. The second case concerns Cango Cave. A simple monitoring network has been installed in September 2000 to be operated for one year. It consists in about 15 rugged data loggers distributed along the cave. Air and water temperature, carbon dioxide concentration, and relative humidity are measured and the values are transferred periodically by a shuttle into a computer outside the cave. A totally automatic monitoring network will be installed in the future after the results of the first simple network are achieved.

A critical description of Carlsbad Caverns, New Mexico, USA, in 1931, 2012, Craven, Stephen A.

An account is given of the 1931 visit of the young South African academic geographer Vernon Forbes to the American show cave Carlsbad Caverns. In a subsequent newspaper article he compared the busy Carlsbad Caverns to the much less frequented Cango Cave in South Africa, which he had never seen.
