In 1895 Martel founded the French ‘Société de Spéléologie’, arguing that ‘speleology’, which had been previously considered a sport or a singular eccentricity, should be recognized as a fully-fledged science – “a subdivision of physical geography, like limnology for lakes and oceanography for seas.” A prolific author, he edited Spelunca, his Society’s bulletin, and wrote books about his own cave discoveries. In 1907 the French Academy of Sciences awarded him the grand prize for physical sciences, and in 1928 he was elected president of the Geographical Society of Paris. By the time he died in 1938, aged 78, the grand old man of speleology had personally probed nearly 1500 caves, hundreds of which had never been entered before; his technical innovations had become standard equipment for other cavers; and above all, his persistence and dedication had created a framework within which the seedling science of speleology could develop and blossom.
Meanwhile, the systematic documentation of caves had also started in Britain, with the formation of the Yorkshire Ramblers’ Club in 1892. Under the influence of S.W. Cuttriss, dubbed ‘the scientist’ for his assiduity in recording the group’s findings, its members drew up surveys of the caves they explored, and kept notes of temperatures, altitudes and geographical features.
The great exploration challenge of the day was the awesome Gaping Gill, a pothole high on the slopes of Ingleborough Hill which had been plumbed to a depth of 110 m, but had never been descended. The main obstacle to its exploration came from Fell Beck, an icy stream which cascades down the entrance, filling it with spray and extinguishing any flame which might light a caver’s descent, as well as half-drowning him. A local man, John Birkbeck, had made two heroic, but unsuccessful attempts to descend the pit in the 1840s, after digging a trench to divert the Fell Beck to another sink. His first try nearly proved fatal, when strands of his rope were severed on a rock ledge, but on his second attempt he reached a ledge at 58 m which now bears his name. Yorkshire Ramblers’ member Edward Calvert took up the challenge and had almost completed his own preparations for a descent on rope ladders in 1895, when Martel arrived on the scene, hot-foot from London where he had been invited to address an International Geographical Congress on cave-hunting methods.
As something of a celebrity, Martel was encouraged by the lord of Ingleborough Manor to have a crack at the great pothole and given the support needed to refurbish and extend Birkbeck’s trench. On August 1, before an eager crowd, Martel knotted together his lengths of ladder and lowered them into the darkness. As he climbed down the four metre-wide shaft he was rapidly enveloped by “half-suffocating whirls of air and water” which soaked his clothes and the field telephone which he relied upon to communicate instructions to the back-up team who controlled his safety line from the surface. The cascade redoubled 40 m down and he had to descend through a “frigid torrent gushing from a large fissure”. Pausing on Birkbeck’s ledge to untangle the huge heap of rope which had lodged there, he continued into the unknown depths below. Sixteen metres on, the walls of the shaft suddenly receded and Martel found himself swinging like a pendulum near the roof of an immense chamber nearly 160 m long by 30 m high. He alighted on the floor only 23 minutes after he began the descent, and characteristically at once set about measuring and sketching his discovery. For an hour and a quarter, the Frenchman revelled in the spectacle of the “Hall of the Winds”, Britain’s largest underground chamber from whose roof the waters of the Fell Beck tumbled “in a great nimbus of vapour and light”. There was a certain sense of nationalist triumph too: “The most pleasant feature was the thought that I had succeeded where the English had failed, and on their own ground.”

Martel’s descent of Gaping Gill received wide publicity and awakened an interest in the possibilities of cave exploration in other parts of Britain. A group of Derbyshire rock climbers calling themselves the Kyndwr Club started to explore the caves of that county and further afield. One of their leading spirits was Dr E.A. Baker, a native of Somerset, but at that time resident in the Midlands. He was a colourful and influential character, an academic who later became director of the School of Librarianship in the University of London, but whose interest in caving was primarily sporting.
At about this time, H.E. Balch, a young postal worker at Wells in Somerset, came across a fragment of reindeer antler in the Hyena Den near Wookey Hole and, inspired by the work of Professor (later Sir William) Boyd Dawkins, at once threw himself into a study of all kinds of archaeological and fossil cave sites on Mendip. Soon Balch had founded the Wells Natural History and Archaeological Society and started the collections which eventually grew into Wells Museum. The subsequent arrival on the Mendip scene in 1902 of Baker and his colleagues from Derbyshire led to a long and fruitful collaboration, during which many of Mendip’s greatest caves were dug open and explored. Both Balch and Baker were prolific writers and their publications, spread over several decades, played a large part in stimulating an interest in caving during the early part of this century. A number of clubs began to appear which cheerfully combined a scientific and sporting approach to caving, setting a pattern which has continued to the present day. Scientifically motivated ‘speleologists’ still recognize their dependence on sporting cavers for much of the initial exploration and often for support when working in the more exacting situations. Many are in any case themselves sporting cavers, or were in their younger days. On the other side very few of those whose motives are primarily sporting are completely uninterested in the whys and wherefores of the natural features which provide them with their sport. They also appreciate that scientific understanding increases the chances of finding more caves.
There are few completely unexplored places anywhere on the surface of the earth and none in a country such as Britain; but caves hold out the promise, or at least the hope, of completely new discovery. Most cavers must sometimes dream of one day discovering a new cave, or an extension to a known one, and of being the first to gaze upon whatever wonders it may hold. If these are the things which provide motivation for caving as a sport, they are nearly always reinforced by at least some measure of scientific curiosity, and most cavers combine the two in varying proportions.
In the years after World War II, the popularity of caving, as of so many other active pursuits, increased enormously in many parts of the world. In Britain the 1950s and 60s in particular saw a great proliferation of caving clubs and, although some of these were ephemeral, the overall level of interest and activity has remained high. Perhaps the most important development in British caving in the early post-war years was the opening up of South Wales as a major caving region. Up until 1936, cavers had taken surprisingly little interest in the area considering that Porth-yr-Ogof had been known for hundreds of years and Dan-yr-Ogof had been discovered and explored as far as the waterfalls in 1912. It was to these two caves that experienced cavers from Yorkshire and Mendip first turned their attention in 1936 and interest in the area developed rapidly. By the time that caving came to a virtual halt with the outbreak of war in 1939, the potential of South Wales was apparent to all. In 1946 the South Wales Caving Club was formed and within a few months two of its members, Peter Harvey and Ian Nixon, dug their way into the lower end of the great Ogof Ffynnon Ddu cave system on the east side of the Upper Tawe Valley. Initially rapid exploration was halted by a series of sumps (flooded sections of passage) and it was not until 1966 that a dig in the upper levels of the cave gave access into the vast maze of OFD II. A rush of new discoveries followed in quick succession over the next year, extending the vertical range of the cave to 300 m and its total length to around 40 km, making it Britain’s deepest and longest cave system. (Although cave divers have since linked up various parts of the Ease Gill system in Yorkshire to give it the number one position with an overall passage length of over 70 km).
