Caving in the Abode of the Clouds, Meghalaya 2019

Simon Brooks

2019 saw multi-national Caving in the Abode of the Clouds Project, Meghalaya make yet more excellent progress in its 27th year. With 12.3kms of new cave passage explored consisting of magnificent shafts and stunning river passage this took the cumulative total of passage explored by the project to date past the 500kms mark. Not bad for a part of the world that was originally thought to have limited speleological potential. This years expedition began by further exploration of Krem Puri (the worlds longest sandstone cave) and an event to equip young Meghalaya Cavers with equipment and skills... read more

Return to Pakistan (Cave Exploration in Pakistan 1990 to 2018)

Simon Brooks

Pakistan is a colourful, varied, interesting and hospitable part of the world, often misunderstood, but with a great variety of stunning scenery and some significant karst areas. From 1990 onwards systematic cave exploration as an enduring partnership between the Orpheus Caving Club and the Quetta (Baluchistan) based Chiltan Adventurers Association, Balochistan (CAAB) has yielded 139 known caves with a cumulative passage length of 6,370m. This lecture gives an overview of the cave exploration to date and focuses on the most recent visit in December 2018 where despite challenging conditions another 6 caves were explored yielding a modest 140m of... read more

Peak District Update 2018 to 2019

Simon Brooks

You would think its all being found by now in the Peak District. However, mining (sic) through available material, tapping up regular contacts/informants and chance meetings has revealed that there has been plenty going on. Exploration in the Peaks multitude of mines, often associated with, and intersecting much, 'natural' has once again yielded some interesting finds. The larger systems such a Peak Cavern, P8 and Giants continue to turn up little gems and the ongoing digging site such as Bull Pot and Water Icicle continue to make progress. This lecture gives whistle stop overview of... read more

Mobile Handheld 3DLaser Scanning - Cave Surveying of the Future

Madphil

Until the last decade, cave surveying was a pretty simple affair; the measurement of a baseline using a tape, compass and inclinometers, guestimation or actual measurement of passage dimensions (LRUD), followed by the sketcher drawing an "Artists impression" of the cave passage either to or not to scale. This data would then be put into both cave surveying and drawing packages to produce a final survey. Dependant on the skill of the sketcher, these "Artists impressions" could be at best similar or at worse bare no resemblance to each other at all!

The advent of laser distance measurement and... read more

North Wales: the Fifth Region

Dr Rostam Namaghi

If you know Dr Namaghi then you know that this will be at best a rambling and haphazard stream of consciousness, interspersed with pictures and tangents of a confusing nature. He happens to be a proud Gog (a North Walian) and so, with a slight touch of bias, tell you why it is the jewel in Britain's underground crown. The talk will recount his misadventures over the last few years in:
- the search for Karst on Anglesey
- the Great Orme
- Snowdonia (it's not just Croesor Rhosydd!)
- Ogof Hesp Alyn & the Alyn Valley Caves
- the diving of Powell's lode (cave... read more

Visualising Cave Sound Workshop

Phil Wolstenholme and Dominika Wroblewska

The workshop will feature selected tracks (or track extracts depending on timing) from a collaborative sound work 'The Lure of the Hole' by Phil Wolstenholme and Dominika Wroblewska, utilising natural cave sounds to create six separate pieces. The sounds include rocks, mud, water and vocals , and were recorded in 3D sound to best replicate the cave environment. Participants will be invited to draw their listening experience in real-time using provided materials, and a question and answer session will follow.

Progress with the British Cave Monitoring Centre

John Gunn

In 2018 the trustees of the BCRA and the Buxton Civic Association signed a Memorandum of Understanding with the objective of establishing a British Cave Monitoring Centre (BCMC) at Poole’s Cavern (Buxton) "to monitor cave climate and environmental conditions over a prolonged period and to facilitate cave related study and scientific research". Gemini Data Loggers UK who manufacture Tinytag data loggers very generously sponsored the BCMC by donating their latest radio logger system together with probes to measure air temperature, pressure and drip rate data in the cave and rainfall, temperature and humidity outside the cave. The data from within... read more

Cavers' Just a Minute

Peter Glanvill

Hidden Earth needs a bit of humour so I have, for the last few years, endeavoured to inject some into the proceedings. Last years JAM was well received and slightly revamped I would like to do it again. Subjects will, again be of topical interest.

Mulu 2019, Anglo-Malaysian Caving Expedition

Les Williams

In April 2019, a team composed of UK, Malaysian, German and American cavers attempted to find the much hypothesised but somewhat elusive connection between Racer Cave and Cave of the Winds, other objectives were to attempt to connect Lagang's Cave to Racer/Easter and to attempt to connect Sago Palm to Easter.
All these connections were imminent at the end of the 2017 Expedition so they must surely go this time. Did they succeed?

From snow to past alpine climate: what ice caves tell us.

Tanguy Racine

The infall of snow in open pit caves in an alpine environment sometimes leads to the perennial accumulation of ice underground. These 'cave glaciers' usually also contain macro-fossils, whose dating suggests the preserved ice reaches up to 5000 years old locally.

With the help of an international team of researchers based in Innsbruck, Austria, Tanguy, currently a student at the local university, has visited several of these 'sag-type' caves to investigate their potential for reconstructing a record of past historical climate in the European Alps. The research sites are mainly situated in Austria but also include a Slovenian ice cave.

Tanguy will... read more

Medusa's Maze - CUCC unravels the mysteries of Austria's second longest system

Tom Crossley and Becka Lawson

Cambridge University Caving Club returned to Austrian's Dead Mountains (the Totes Gebirge) in 2019 to be greeted by the biggest snow dump for years. This blocked our top camp bivvy to almost the roof, buried 3m deep the entrance to one of our main caving objectives and, combined with relentless rain, it hammered moral. Plans were laid then re-laid until we hit pay-dirt, deep under the northernmost extent of our main, Schwartzmooskogel system. Here, we extended Balkonhoehle into a whole new horizontal level. Meanwhile, far out in the wilds of the Plateau, our new cave, Homecoming, romped off into empty... read more

CHECC Roundup 2019

Botch

It's the question on everyone's lips: What have those crazy students been up to this year? Perhaps something revolutionary like hosting an event in a Peak District school? Maybe they also had two smaller events as well? But did they go caving? You bet they did. They probably did some drinking too. And you can be sure they went abroad and found some new caves.

I'm sure you have a general idea of what we've been up to, but come have a sit and look at some pictures of young cavers having fun, and we'll have a chat about what we... read more

Photoshop Workshop

Jerry Wooldridge

Photoshop workshop, looking at using layers; layer masks; adjustment layers.

Suitable for a small number (6 – 9) of people who have some experience with Photoshop, but find the concept of layers difficult. The workshop would be for about 2 hours (Saturday). Using layers particularly to combine a number of images & using layer masks in that process. Using adjustment layers for ‘non destructive’ editing of a photograph. Adjustment to the image itself is destructive as information is lost.

he idea of the workshop would be to bring your own laptop with PS on, & preferably a couple of your images to... read more

Fairy Holes - Weardale. The history and continuing exploration of a cave that was almost lost forever.

Adele Ward and Andrew Hinde

Fairy Holes - Weardale was first entered prior to 1882. The main exploration took place in the 1950's and 60's before quarrying operations denied access to the cave for nearly 50 years. This classic North Pennines stream cave was described during exploration as "second only to Mossdale in its severity".

The cave is a salutary lesson in what can happen when Statutory Protection under the Wildlife and Countryside Act bumps up against Big Business and the economic future of a local community.

Recent explorations by the late Ian Cummins and Adele Ward have added over 600m on unrecorded and new passage to... read more

Greenland Caves Project 2019

Dr Hazel Barton

During July, 2019, the Greenland Caves Project returned to Northeast Greenland for a three week interdisciplinary research and exploration expedition. The 9-person, 7 nationality team, included researchers from the Universities of Innsbruck, Akron, Oxford, and Sheffield. Four areas were worked and explored from three base camps, and with the availability of a helicopter, the team were able to cover significantly more ground than they would have otherwise done on foot. Still, the going was often tough, with steep scree slopes and exposed ledges needing careful navigation. Over 30 holes/caves were documented and explored, of which 5 yielded significant cave passage.... read more

Becoming French - 4 Years of Exploration in the Vercors with the SGCAF

Jeff Wade

To many the Vercors is seen as the ideal place for classic caving, but go on a few caving trips with the locals and it is clear that it is not an area for just holiday caving. After four years of living in Grenoble and caving with the SGCAF, Jeff gives an insight into some of the discoveries that have been made in recent years in his club and what caves may become the new classics. Now virtually French, he will also give an understanding into how French clubs function; what is the drink of choice? do they... read more

3D modelling of Ironstone and Jet workings in Cleveland

Chris Twigg

Ironstone mining which took place in Cleveland between 1848 and 1964, generated an impressive paper trail of mine abandonment plans and company records. In sharp contrast, the death of Prince Albert in the early 1860s triggered an explosion in jet mining, which generated no plans and virtually no written records. The Heritage Lottery Funded 'Our Industrial Heartland' project generated 3D models of these two sets of geologically adjacent workings. In the ironstone via geo-referencing of historic plans in GIS software, whilst in the jet workings, local mine and caving clubs used a DistoX paperless surveying system and Survex software.... read more

The Weird Microbiology of Mulu

Dr Hazel Barton

Exploration throughout the caves of Gunung Mulu National Park has revealed a host of deposits of unknown origin. During the Mulu ’19 expedition we examined some of these deposits to determine whether they were formed through geologic processes, or whether microbiology could be involved. Our results, based on preliminary field observations, suggest that there are a number of formations that are created by microbial processes. In addition, the temperature, high humidity of the caves, and extensive deposits of bird guano throughout the caves are possibly driving microbial processes that have not previously been described in caves. ... read more

Shannon Cave, Ireland: High level explorations 2017-2019

Petie Barry

Shannon Cave is an 8.5km long cave system straddling the border between Northern Ireland and the Republic of Ireland. A magnificent system, it consists in the main of a huge river passage which can be followed for over 3.5km. It is also notable for significant quantities of high-level passages which effectively duplicate the stream passages below

First discovered in 1980, explorations between 2005 and 2010 doubled the known length of the cave to over 5km in length. A new phase of exploration from 2017 onwards has seen another 3km of passage added to the system, largely due to the systematic surveying... read more

Land Down Under: Anglo-Irish Caving Expedition to Tasmania 2018-19

Petie Barry

Mount Field National Park in Tasmania contains many of Australia's deepest and most dramatic caves. Typically active stream caves with much vertical development, they approach depths of 350m+ and up to 20km in length. With many of the sinks in the rainforest of the Florentine Valley, and a single major rising at the Junee Resurgence over 10km away, there is potential for a huge cave system to be discovered. Despite decades of exploration by local cavers, little of the low-level master-cave conduits has been discovered, and large breakthroughs can be made with relative ease. With expedition leader and former Australian... read more

Reasons for, and perceptions of access restrictions to caves and recreational mines within the mainland Britain

Robert Middleton

Access to caves and recreational mines has been a divisive issue in mainland Britain since the growth of caving as a pastime following the end of the 2nd World War. The subject has been further heightened in recent years by the campaign to include caving within the Countryside Rights of Way Act. This lecture highlights the results of masters dissertation research which used a mixed methods approach including interviews, questionnaires (advertised on UKCaving thanks) and case study analysis to increase understanding of the myriad of access restrictions present to caves and mines in Britain, and cavers’ perceptions of these restrictions.... read more
