Book excerpt: This book is mainly concerned with the geomorphological aspects of caves - karst hydrology, speleogenesis and the origin of speleothems. Cave exploration was a necessary prerequisite for such studies and its progress is traced from prehistoric times to the systematic regional investigations of the 1 7th century and later. The first extensive work was in Slovenia, stimulated by the practical importance there of karst hydrology for water supply and flood control. Large karst springs had long attracted attention and several hypotheses had already been advanced; according to some they were supplied by water raised from the sea, others explained them by condensation and finally their source as rainfall was accepted. The study of intermittent karst lakes led eventually to the postulation of what amounted to a water table.A true understanding of speleogenesis and the origin of speleothems depended on a knowledge of the chemistry of limestone solution, which in its tum depended on the rejection of phlogiston at the end of the 18th century. Before that time only mechanical erosion was normally conceived as a means of removing particles of solid rock and subsequently redepositing them to form speleothems, although a few people earlier in the century had involved an unspecified "aerial acid". There were also several more primitive theories including the formation of caves by tectonic "catastrophes", by erosion as the water of Noah's Flood drained back underground, and the inflation of cavities in still soft limestone by decomposition gases. For many years speleothems were thought to possess a low form of life, growinglike plants rather than by accretion.After the action of carbon dioxide in speleogenesis was appreciated a new question arose - whether caves could be formed in the saturated zone or whether they were due solely to vadose water. For many years the problem was not recognised but violent controversy was taking place over it by the end of the 19th century.

Available in PDF, EPUB and Kindle. Book excerpt: A captivating introduction to the world's most fascinating caves, Caves, Revised Edition explores every nook and cranny of these nature-made creations—including lava caves, sea caves, and glacial caves—from Kentucky's Mammoth Cave, to the amazing Paleolithic paintings of Lascaux, to Fingal's Cave of Scotland, which inspired Mendelssohn's Hebrides Overture. Engrossing facts about the geologic origins of these underground voids; their astonishing speleothems, or formations, such as stalactites and stalagmites; and the microscopic extremophile organisms that dwell within are enhanced by exciting photographs and a wealth of other educational resources for further exploration.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights some of the most difficult and persistent exploration ever undertaken in the United States – in Burnsville Cove, a small limestone valley in west-central Virginia – while at the same time reviewing the scientific discoveries made in the area’s 116 km of caves in the course of 50 years. Overall, the book offers a unique combination of exploration and science by a conservation organization specifically dedicated to the preservation and study of the caves.

Available in PDF, EPUB and Kindle. Book excerpt: Caves are dark, underground hollow spaces with relatively constant temperature, high humidity, and limited nutrients. Many caves are associated with karst topography, which is formed by the dissolution of soluble bedrock, such as limestone, dolomite and gypsum, in areas where groundwaters are undersaturated with respect to the minerals in the host rock. Karst landforms spread widely, accounting for approximately 20% of the earth’s dry ice-free surface (Ford and Williams, 2007). As a typical feature of subsurface landscape, karst caves develop globally, with over 50,000 distributed in the United States (Barton and Jurado, 2007). China also has a large contiguous karst terrain, and the Yunnan–Guizhou plateau in the southwest developed most karst caves, among which the longest cave exceeds 138 km (Zhang and Zhu, 2012). Many caves are relatively shallow and form near the water table in karst terranes, although some caves develop by deep-seated hypogenic process at substantial depths and by process other than dissolution such as lava flows. Caves are oligotrophic ecosystems with less than 2 mg of total organic carbon per liter, yet host flourishing microbial groups (Figure 1A), with an average number of 106 microbial cells per gram of cave rock (Barton and Jurado, 2007). The study revealed a high diversity within Bacteria domain and Proteobacteria and Actinobacteria were abundant in oligotrophic cave samples of air, rock, sediment and water. Chloroflexi, Planctomycetes, Bacteroidetes, Firmicutes, Acidobacteria, Nitrospirae, Gemmatimonadetes, and Verrucomicrobia also accounted for large proportions of the total microbial community in caves (Wu et al., 2015; Zhu et al., 2019). In some organic cave samples such as biofilms in sulfur cave, bat guanos, spiders’ webs and earthworm castings, Mycobacterium was prevalently detected (Modra et al., 2017; Sarbu et al., 2018; Hubelova et al., 2021; Pavlik et al., 2021). Over 500 genera of fungi, such as Penicillium, Aspergillus and Mortierella have been reported in caves (Vanderwolf et al., 2013), and new fungal species were identified from cave air, rock, sediment and water samples (Zhang et al., 2017, 2021). These microbial communities contain novel diversity, and promote important biogeochemical processes. With no sunlight, microorganisms in cave environment cannot perform photosynthesis, and are intensively involved in the biogeochemical cycles of carbon, nitrogen, sulfur, and metals such as Fe and Mn to offset the lack of exogenous nutrients and energy.

Available in PDF, EPUB and Kindle. Book excerpt: In 1883, wearing a sixty-pound suit sewn from leather boot-tops, a wanderer known only as the Leather Man began to walk a 365 mile loop between the Connecticut and Hudson Rivers that he would complete every 34 days, for almost six years. His circuit took him through at least 41 towns in southwestern Connecticut and southeastern New York, sleeping in caves, accepting food from townspeople, and speaking only in grunts and gestures along the way. What remains of the mysterious Leather Man today are the news clippings and photographs taken by the first-hand witnesses of this captivating individual. The Old Leather Man gathers the best of the early newspaper accounts of the Leather Man, and includes maps of his route, historic photographs of his shelters, the houses he was known to stop at along his way, and of the Leather Man himself. This history tracks the footsteps of the Leather Man and unravels the myths surrounding the man who made Connecticut’s caves his home. Ebook Edition Note: Six of the 111 illustrations have been redacted.
