Description

Herbert Daniel Gebauer - 06/01/2018

About 15 or 18 cave entrances (mostly potholes, generally 50 to 60 m deep, one free climbable) drop into a dendritic pattern of stream cave passages (allegedly 18 km long), which all drain to the resurgence entrance to Krem –>Ticha. ETYMOLOGY: The cave appears to be called after an -um- (stream of water) named after the -dieng thluh- which is a tree whose bark is very useful in making ropes, etc. (SINGH, N 1906: 234). To interpret the Synteng Khasi (Pnar) cave name as -um thloo- or -um thlu- (synonymous with the Khasi -um thliew- = water of hole or hole water) seems to be unlikely as there exists neither a -hole water- (um thliew) nor a -water hole- (thliew um) at this cave entrance or in it's vicinity. So far (April 2008), I saw the cave name of Krem Umthluh (Tongseng) called and spelled, edited or printed as Krem Mtwo Ende, Barbara Anne (2007.02.10 Mss: Krem Mtwo).

Krem UMTHLUH, Tongseng, no. 1 itself opens as a shakehole (collapse doline) in a closed depression surrounded by partly buried karst pinnacles. It probably functions as a seasonal sink and leads, after a series of loose, awkward climbs and unlikely squeezes --first mastered by Tony Jarratt and Allard Harris Diengdoh-- to a basement level of generally joint controlled streamways with a small perennial flow (February maximum circa 3 l/s). Some photographs by Yvo Weidmann are published in ARBENZ & WEIDMANN (2003: 1, 10, 11). SITUATION: On the eastern side of the Shnongrim - Tangnub ridge, below Tongseng village, and near the upper edge of the -tree line- (indicating the upper rim of the forest covered limestone terrain below the grass cvered scarp of the ridge). APPROACH: Ask for a guide to reach the entrance in the jungle. Take either a steep shortcut (footpath) from the pass at the northern end of Tongseng village or otherwise the road descending from the village towards the paddy field covered plains in the upper reaches of the Lunar and Letein (Litang, Litien) valleys. At a point where standing stones can be seen on an open ridge (from the road to the left / north-east), walk into the upper part of a valley, aiming (in spring 2001) for the grove of pine trees on the skyline. On reaching the -Lonesome Pine- in the valley, follow the path down valley for about 100 m to reach a bamboo filled obvious sink among half buried karst pinnacles on the left (northern) scarp of the valley.

CAVE DESCRIPTION 2001b: A short climb down leads to a reasonably well decorated, spider infested series of chambers with a horrific looking vertical boulder ruckle in the floor… [which leads] into a 6 m diameter 'Master Cave.' The main upstream passage was pushed for a couple of kms to a high aven with possible high level passage part way up and climbable with aid. Several kms of wet and dry passages lead off from this, generally in a northerly direction and towards the crest of the ridge, beyond which lies Krem Shynrong Labbit [Krem –>Shyien Khlieh], Krem Labbit (Lum Dait Krong) [Krem –>Labit, Lumdait Kroh] and Krem Risang. Downstream was surveyed throgh lots of spectacular passage to a resurgence (Krem Ticha) and a side entrance in a jungle filled doline (JARRATT 2001: 35) CAVE DESCRIPTION 2001c: … a bamboo filled, dry flood sink. This was reminiscent of Eastwater Cavern and decidedly uninspiring … A short rope climb (later free climbed) led to a decorated descending passage and reasonably attractive chamber with the usual obligatory heteropoda. In the floor of this was a boulder choke with black spaces. The cave was unpleasantly warm and apparently draught free but it was decided to survey it for completion and in the hope that we might salvage a hundred metres from the day. While the others commenced the survey I got the job of trying to find the way on down through the hairy looking vertical choke. The huge wedged boulders, though calcited in places, were frightening to descend through as the movement of one would have brought down possibly hundreds of tons. At a depth of circa 43 m I emerged sweating from the horrors of the chke into a solid walled and roomy phreatic passage with a dry mud floor. After some route finding problems getting back I guided the surveyors back down and this passage was mapped for a few score metres to an attractive chamber and solid choke. Allard [Allard Harris Diengdoh] poked about in an obvious but small and uninspiring sink passage which he found to open up after a few metres. I followed him through a series of small, rimstone floored chambers to reach a fine 2 m high strongly draughting stream passage with static water and a low duck on the LH side. Just before this an awkward inlet led to over 50 m of phreatic passage [note 1] and a circa 20 m high aven. Back in the stream we surveyed for c. 210 m along some superb walking passage and we were about to call it a day when Allard mentioned that he could hear the sound of a stream in the distance. I went on for a look and found a large archway on the LH side of the passage opposite a superb red flowstone bank. Entering this I wa totally gobsmacked to find myself in a 6 m diameter bore tube with a good sized stream flowing from left to right and cascading into a passage opposite the archway giving a four way junction …(Jarratt 2001.02.11 Mss: Cave Log 2001: 11/2/01). … Goon [note 2], Brian and I… set off upstream… and surveyed over 400 m of stunning bore tube with pools, pebble banks and the occasional grotto (including a massive stalactite) until we turned right up a dry inlet over a series of gour. This walking sized phreatic tube was named Waverly Tunnel after a noted Edinburgh landmark and was surveyed easily for another 800 m or so until we got fed up. A 53 m and a 54 m leg indicate the type of passage involved! Most of this had a flat pebble or mud floor with scattered pools containing fish, crabs, and crayfish. A few muddy formations relieved the uniformity in places. This amazing gallery eventually reached an area of avens, inlets and oxbows where we called a halt at an apparently blank wall. I then nticed an abrasive crawl at floor level which quickly led to a huge breakdown chamber —Monolith Hall— and ongoing inlet passage. Part way along Waverly Tunnel the draught reversed direction and near the end a howling gale emerged from a very narrow inlet. Another walking sized inlet (later called Malakoff Bridge and Tunnel) was also briefly investigated and found to be ongoing … Jarratt (2001.02.13 Mss: Cave Log 2001): Dan, Mark and Rhys tidy up a few odds and ends including the gour passage and dry upper level stuff before the duck in the entrance series.Goon, Peter and I joined by Brian and Christian… surveyed on from Sunday's last point. Through the crawl into the large Monolith Hall and along the stream passage beyond which unfortunately soon narrowed and reached the bottom of an aven. We managed to climb this for some 10 m to reach a high level passage where a rope would be needed to safely gain access by lassoing a prominent stalagmite. We then surveyed a blind rift, a short oxow and the strongly draughting Gale Force Gallery which Christian had pushed to an aven. We continued beyond this in a narrow rift passage to the base of another aven —again with a possible free climb that needs protection. A maze of passages nearby – Otter Maze [note 3] – due to a skull found here which was identified by the locals) was not mapped due to lack of time and remains to be done next year (Jarratt 2001.02.12 Mss -Cave Log 2001- 12/2/01). We carried on up the km or so of the main Umthloo streamway to the point where Tom's team had stopped —a superb section of bore passage with lots of wading and a short swim. From the end point Tom, Mandy and Rhys surveyed about a kilometre of upper levels and active inlet streamway leading to an aven which needs climbing. At one point a ferociously draughting hole miraculously spotted at floor level was dug open by Tom to enter a small chamber unfortunately already occupied by a very lively thin snake. Rhys had by now joined him and fearng that the possibly venomous serpent could get past them into the entrance squeeze they were reluctantly forced to stone it to death. It's presence and the strong draught indicated a nearby entrance [Anthony 'Tony' R Jarratt 2002.02.30 Mss: Amendments -Krem Myrliat-]. We continued up the main stream passage for a couple of hundred metres of sinuous canyon to reach a low duck with a howling gale coming through —Wind Tunnel Duck. I popped through this to reach a roomy chamber and large rift passage ending in a short climb up to yet another aven needing a lasso rope and a ladder to reach a higher level canyon visible above [note 4]. Back to our starting point where we surveyed about 300 m of phreatic maze (White Millipede Inlet) with superb gours, stalagmite flows and a few formations. One passage in here also led to a possibly climbable aven and another to a draughting boulder choke. Again, both of these appear to be fairly close to the surface. An inch long white millipede was sen here and lots of open leads were left for next year (Jarratt 2001.02.15 Mss: Cave Log 2001, 15/2/01). Our first job today was to climb into the visible passage at the top of the aven beyond Monolith Hall… A fine passage led on but soon closed down at a calcited blind aven with a hidden pitch down on the LH side at floor level [This leads] … to the floor of a circa 30 m high aven with a grotty bit of passage leading off to a circa 10 m pot where we stopped… Ignoring low, uninspiring inlets and the Otter Maze we headed back down Waverly Tunnel to survey the only walking sized inlet left —on the RH side going in. Luckily it was good stuff and was mapped for 387 m to an area of several circa 25 to 30 m high avens with small ongoing stuff beyond which we had to leave … (Jarratt 2001.02.19 Mss: Cave Log 2001: 19/2/01). The Aquarium is a stooping sized canal well stocked with hundreds of small, white and probably blind cave fish. This amazing passage soon led to a much larger and drier crss passage which was flooded upstream and enlarged considerably, eventually developing into an attractive square tunnel with formations [speleothems], breakdown, a sandstone ceiling and lots of gypsum crusting on the walls. This gave us some good legs and we stopped at an apparent choke above a low streamway crossing below the breakdown: Well over 500 metres of generally impressive and varied passage in the bag. Mandy then crawled through a tiny, previously unnoticed slot behind the choke to emerge in an even bigger, 9 to 10 m diameter passage above and heading north. The place was really opening up … There are scores of side passages on the way which have not been explored or surveyed (Jarratt 2001.02.20 Mss: Cave Log 2001, 20/2/01). … abseiling down Krem Myrliat entrance shaft, past the dead snake and through Tom's dug out crawl into the big stuff in upstream Umthloo -- saving us about 3 hours of caving to and from the boulder ruckle entrance. At the Aquarium stream junction Mark,Dan and Lindsay left us to survey up the other stream inlet for c. 80 m to Fisherman's Aven where Dan caught some cave fish for his speleobiological studies. They then surveyed some 130 m of grotty side passages… At the far end of the Aquarium Thomas, Anja and Peter commenced surveying the passage on the right —muddy, wet and not very long but beautifully decorated in places. Another couple of inlets were also mapped but became equally grotty. We carried on to our last station and surveyed through Mandy's crawl into the big breakdown passage beyond. Dead straight, this continues for circa 180 m with an awkward climb up and then down to avoid a foul looking duck about 2/3rds of the way along. This was surmounted with the use of a rope and etrier only just long enough to reach the floor. Beyond this the passage degenerated to muddy crawls which obviously flood completely in wet weather. Thankfully these soon broke out into a big canyon which was followed to a Y-junction. The RH passge became a climb up boulders with a cold draught whistling out of the huge boulder choke ahead. There seems to be a high aven in the roof just before this. The LH passage also ended in a totally boulder choked canyon (Jarratt 2001.02.22 Mss: Cave Log 2001, 22/2/01). CAVE DESCRIPTION 2005: My last trip of the [February 2005] expedition was to the awesome system of Krem Umthloo --my -baby--- in an attempt to smash up a hanging boulder preventing access to a 10 m high inlet which could be seen beyond. This lay at the end of International Schweinehund Passage and not too far from the boulder choke entrance to the cave. … Not having been able to scrounge any explosives I was armed with a hefty hammer and set to on the rock which was calcited into the ceiling of a low crawl. Suddenly the whole boulder dropped out with an earth shaking thud … I was just able to shift it enough to squeeze past into the big stuff beyond and the others eventually followed. Sod's Law then decreed that this fie passage soon ended at a calcited aven with an unpleasant crawl to one side which became too tight. It also became too toxic after Quentin inadvertently set fire to the tape with his lamp! Raplang was by now totally mind blown by the curious antics of the Ferengis and we, in turn, were equally mind blown by the noise of what could only be described as loud snoring emanating from a low duck at the base of the aven. The source of this weird and somewhat disturbing phenomenon will have to wait another year to be discovered but is doubtless related to siphoning water or an intermittent draught. It just begged the name of Snoring Duck Aven (JARRATT 2005). TACKLE: Handline for a 2 m drop from the entrance doline into the first dark bit of the cave. PROSPECTS 2005: … well over 100 [unspecified] leads remain to be explored and the possibility with a link to the potentially huge Krem Synrang Labbit system [i.e. Krem Synrang Labit] to the north is definitely on the cards (JARRATT 2006: 16).

Therefore went fortea and cakes (Hogson 2002 Mss: SUTDIARY.WRI, 2002.01.13). 2002.02.14, trip 30: Kremm [sic!] Umthloo Myriat [Myrliat] entrance, Nicky, Andy, Mark. Returned to continue up stream [sic!] survey. 17 m of freatic [sic!] passage gained from last survey station to choke. Rift at end free climable [sic!] for 10 m, could see black space in aven above but not hopeful. Bats seen here (Hogson 2002 Mss: SUTDIARY.WRI, 2002.01.14). 14.02.02 MB, AH, NB 17 m (Brown 2002.05.05 personal correspondence). 2002.02.15, trip 31: P- Ludwig and Anthony 'Tony' R.

SPELEOMETRY 2002: Survey length: 12,660.89 m, vertical range: 190.99 m (+0.00 m / -190.99 m). 2003.02.07, trip 36: Anthony 'Tony' R. Jarratt and Katrin 'Trillerameise' Zipfel 'surveyed' 111.3 m in Krem Ryman (total: 12,772.19 m). 2003.02.13, trip 37: JARRATT (2003): In the … stunning Umthloo system … Annie and I, accompanied by the aptly named Bat, eventually pushed a three year old promising lead into circa 100 m of squalid and aquatic misery, thankfully left unsurveyed as your scribe had no lead in any of hs three pencils --no change there then! Roger also earned the 'free diver of the year award' for rescuing a sunken tackle bag in the same cave.2003.02.21, trip 38: T.

SPELEOMETRY 2003: Survey length: 13,413.04 m. 2005.02.16, trip 43: Fraser showed Dan, Christian, Peter and Graham to Krem Umthloo, where they collected nd photographed creatures (Brooks 2005 Mss: Meghalaya Diary).2005.03.01, trip 44: Anthony 'Tony' R. Jarratt (2005.03.06 Mss: Cave Log, vol. XII 27-28, 1/3/05), Quentin 'Cooper' Cowper and Raplang Shangpliang: This was the last trip of the [2005] expedition and a bit of a personal treat in my favourite Meghalayan cave system. 'Iwonder how they knew, I'd been down Krem Umthloo. Now I've got the cramp, I am back in camp –where– smoke gets in your eyes.' The area around the cave entrance was now cultivated and the old way in full of vegetation making entry via the sloping entrance nearby the best way in. Unfortunately today the team were particularly dopey with Raplang [Shangpliang] staying outside to eat his breakfast, Greg [Gregory D. Diengdoh] failing to organize him and Quentin ['Cowper' Cooper] just not in the mood. Eventually we reached the river passage and I had a look upsteam to find most of the stalagmites broken by the locals were mining –either removed manually or more likely swept away in the monsoon. We then headed downstream where I failed to find the easy dry route and ended up laddering over a stl boss. Soon gaining the International Schweinehund Passage we pressed on to the awkward squeeze where Quentin went on strike. I got fed up and carried on down the ladder to the boulder blocked crawl under the stal floor where I started chipping away stones cented into the ceiling and eventually the metre long hanging rock itself. Suddenly the whole thing fell off with a [rewarding?] thud that even woke up Quentin and after a bit of manoevering I crawled past it into the open passage seen on the last visit. This was high walking sized stuff as foreseen and after lots of [faffing?] by Team Dopey we were eventually all assembled and set of to survey the prophezized kilometre or so. Alas it was not to be as about 20 m further on we reached a 15 m high calcited aven, where climbing kit would be needed to progress. The discovery was, however, marked by the incredibly weired sound of 'snoring' issuing from a tiny waterlogged hole near a low static duck. This prompted the name of SnoringDuck Aven but we were unable to ascertain what caused this curious phenomenon –draught of flowing water both being possibilities. A possible climb above this needs checking out in the future. Our next job was to survey along a hands and knees, mud-floored phreatic tube heading into the distance. The team started off in reasonable spirits but after 100 m or so they got fed up. The stench of burning plastic when Quentin got the tape too near his lamp didn't help. The passage became very slimy and I pressed on for a look to find it got too small some 30 m further on … We retreated in relief, surveying the last agonizing legs through the dug crawl to the top of the pitch on the way …Brooks (2005 Mss: Meghalaya Diary) was told that Anthony 'Tony' R Jarratt, Raplang Shangpliang, Gregory 'Greg' D. Diengdoh and Quentin 'Cooper' Cowper …went in Krem Unthloo to push a boulder blockage at the end of 'Surveyor's Dream'. They surveyed 132.63 m of muddy crawling beyond. Brooks (005.10.05 Mss: Meghalaya 2005 Survey Summary) recorded that ARJ, GD, QC and RS 'surveyed' a total of 132.63 m of fully accumulated distances. SPELEOMETRY 2005: Survey length: 13,545.67 m. 2006.02.25, trip 45: One of the worst damaging tourist trip (note 5) ever undertaken in the history of Meghalaya Cave exploration perfomed Anthony 'Tony' R Jarratt (Bristol Exploration Group and Grampion Speleological Society) assisted by Imogen Furlong (Sheffield University Speleological Society) and Neil Pacey (Red Rose Cave & Pothole Club): This was a working tourist trip to show Imo and Neil one of the finest systems under the [Shnongrim] Ridge. We found the entrance easily and dropped down through the choke to the main streamway. My collegues were very impressed with this and the rest of the cave. After a quick look up Waverly Tunnel we continued on upstream and through three swims where we used a single life jacket on a cord. One each would have been better and wetsuits more appropriatethan dry gear! After turning right at the Krem Ryman junction we continued on through stunning passage to the Aquarium. Once through this we looked for passages on the right which could yield a connection with Krem Synrang Labbit [better: Krem Synrang Labit] to the north but had come too far for the thre we intended to check. We did enter Letter A Gallery where a new aven on the left was entered after Neil broke the obstructing formations. He sketched this and we carried on to the 'sump' at the end. Imo found this to be a formation filled wet crawl and did a sterling job of smashing her way through the stal [note 6] to enter a muddy but well decorated, walking sized passage which was surveyed for 79 m to a mud and calcite choke. One low stream outlet was not pushed due to lack of time. We then left a crowbar and hammer near the entrance to the Aquarium and made the long, cold and wet journey out. Further pushing in this area needs to be done via Krem Myrliat. A great sporting tripbut very cold. A crawl beneath lots of bats proved an entertaining interlude! (Jarratt 2006.03.04 Mss: Cave Log, vol. XIII: 25/2/06). 2007.02.10, trip 46: Barbara Anne am Ende (2007.02.10 Mss: Krem Umtwo) and Peter Glanvill walked down from Tongseng eastwards and met a wood cutter named Mecka (or so) who, upon being asked 'krem' (cave), indicated a vertical walled doline and small (sic!) cave entrance (unidentified shape, size, position) of a Krem Mtwo that corresponds either to the explored Krem Umthuh (Tongseng) 2 or to a not yet unexplored Krem Umthluh (Tongseng) 3. 2007.02.21, trip 47: Anthony 'Tony' R. Jarratt, Peter Ludwig and Robin F. Sheen … were back at Krem Wah Lukor 2 and the final pitch was dropped into the farthest upstream end of the superb, 14 km long Krem Umthloo – the writer's baby! This was Expedition [read: February 2007 excursion] connection number eight and particularly satisfying as it was likely to herald further exploration in this very fine, and far rom finished, system. 2007.02.24, trip 48: Anthony 'Tony' R. Jarratt, Amanda 'Mandie' or 'Mandy' Edgeworth and Neil Pacey rebolted down the shaft into Krem Umthloo and went upstream in Letter C Gallery to push a flatout crawl in mud to a calcited aven containing some mushrooms. They continued the crawl to muddy aven, then entered the side of a passage in the west end of Krem Synrang Labbit. They derigged on the way out. This combined 'Southern ridge system” is now 18 km long and thus the third longest cave in India (Brooks, S J et al. 2007.03.01 Mss: Diary2007.doc). 2007.11.25, trip 49: Arbenz, T (2007.11.24 Mss: Um Thloo finds): Digging in old papers is sometimes really like archeology: Looking up loose 2006 survey sheets of Krem Labit Khaidong in search of sketches of entrance passage, I found 4 sheets of a 2006 trip to Um Thloo lettre A gallery (stuck by mud to a pack of muddy survey sheets done by Imogen). The total of this addition is 79.09 m. There is also a quite sable sketch which I will keep in store, and there are 2 more sheets with sketches but no data - belonging to Um thloo. Will keep those for further discussions with the authors ;-) The addition pushes the total of Um Thloo to 13,492.13 m. Relevant part of 2006 diary: 25th Feb: Jrat, Imogen and Neil went into Umthloo and pushed a low crawl to gain some walking passage. 79 m surveyed.SPELEOMETRY 2007: Survey length 13,492.13 m (note 7) at a vertical range of 190.99 m (+0.00 m / -199.99 m). 2008.02.05, trip 50: Jean-Pierre, Peter and Rolf went to Krem Wah Lukor 3 to rig the new shaft, Scurion Pitch c50m was surveyed and connected to Krem Umthloo (Brown et al. 2008 Mss 'Meghalaya 2008 diary' entry Tuesday 5th February). 2008.02.17, trip 51: Rolf Siegenthaler, Shary Ghazi (Sharareh Ghazy), Axel Rosen and Jean-Pierre Batholeys surveyed the 111.57 m of the connection from Krem Um Thloo to Krem Synrang Labbit (Brown et al. 2008 Mss 'Meghalaya 2008 diary' Sunday 17th February) or Krem >Synrang Labit (Shnongrim). SPELEOMETRY 2008: Survey length 18,092.06 m (note 8), vertical range 213.33 m (+0.00 m / -213.33 m). BROWN & BROOKS (2008: 16): In Krem Umthloo [sic!], an aven of over 30 m height was climbed. With other extensions, this made the system 18,181 m in length maintaining it as the third longest member in the Indian subcontinent. Herbert Daniel Gebauer - 06/01/2018
