Description

Herbert Daniel Gebauer - 06/01/2018

A seasonal swallet. Two gullies join into a doline without identified shape or dimensions: On the north corner there is an active swallet about 10 m deep and 5 m across (Sheen & Ende 2007.02.12 Mss: B4 or After). ETYMOLOGY: No autochthonous, indigenous or locally known name has been identified for a cave which Robin F. Sheen and Barbara Anne am Ende recorded as B4 or After (Sheen & Ende 2007.02.12 Mss) and other sports cavers masked with the Pseudokhasi cave name Krem Lumthymme (note 1) after one of the nearby villages. SITUATION: According to Sheen & Ende (2007.02.12 Mss: B4 or After) at a vaguely described location somewhere on the contour circa 1090 m paralleling north-northeast from the Knee-Wrecker Pots towards Krem Ryngko Lymthymme alias Krem –>Synrem (near ±6.4 m 25°22'20.6”N: 92°31'56.4”E: 956 m WGS84). POSITION 1: (±8 m) 25°22'16.5”N: 92°31'41.8”E: 1046 m (Sheen, R F 2007.02.12, GPS). POSITION 2 (unspecified precision error) 25°22'16.9”N: 92°31'42.0”E: 1024 m (Anoymous 2008 February Mss: Krem Lumthymme (B4)_01.Text). CAVE DESCRIPTION 2008.02.08: Stream sinks though shakedown at base of a large doline [without dimensions] for 20 m to head of 60 m broken pitches. Comfortable walking passage deteriorates into hands and knees over cobbles & sand through glutinuous muddy area to a section of chest deep canals approx. 200 m to a climb up through boulders (Sheen, R F 2008.02.08 Mss: Krem B4). CAVE DESCRIPTION 2008.02.08b: Doline pot hole that takes a seasonal stream (Brooks, S J, undated Mss amendment to Sheen, R F 2008.02.08 Mss: Krem B4). CAVE DESCRIPTION 3: Perfectly nothing has been observed in Krem Lumthymme which was only understood, as if this would matter, to be 1.1 km in length but unfortunately failed to connect into the Liat Prah system (BROWN & BROOKS 2008: 16-17). CAVE CONTENTS: Mudbanks, sandstone cobbles [deleted: warm water] (Sheen 2008.02.08 Mss: Krem B4) TACKLE: 8 m ladder, 34 m rope, 42 m rope, 6 m ladder (Sheen, R F 2008.02.08 Mss Krem B4). PROSPECTS 2008: Continues beyond canals and draughting (Sheen, R F 2008.02.08 Mss -Krem B4- 8/02/08). SPELEOMETRY 2008.02.29a: 1.1 km in length … (Brooks & Brown undated 2008.02.29 Mss: Overview.doc). SPELEOMETRY 2008.02.29b: Total 1103.62; vertical 119.98 (Brown, M W et al. 2008 Mss: Survey Summary). SPELEOMETRY 2015.09.16: Lgth. 1108.83m VR (117.53m) +21.97 /-95.56 (Arbenz, T 2015.09.16 dated -17.9.2015- Lumthymme-B4-plan.pdf). CAVE CLIMATE: Sheen, R F 2008.02.08 Mss: Krem B4) noticed that the cave once had emitted an air current which was draughting out (Sheen, R F 2008.02.08 Mss: Krem B4). CAVE LIFE: Apparently blind albino loaches, shrimps, albino crickets, snot gobblers (Sheen, R F 2008.02.08 Mss: Krem B4). Keywords: Larval stage of fungus gnats (Diptera: Mycetophilidae); Crustacea; unpigmented Orthoptera; unpigmented Cobitidae (Pisces). Krem B4).

History

EXPLORATION HISTORY: 2007.02.12, trip 1: Robin F. Sheen and Barbara A. am Ende (2007.02.12 Mss: B2) noticed a seasonal insurgence without identified name. According to Brooks, S J et al. (2007.03.01 Mss: Diary2007.doc), Barbara and Robin went on a surface recce between Knee Wrecker Pots and the village of Lumthymme. They located 6 pots. 2008.02.07, trip 2: Robin F. Sheen (2008.02.08 Mss: Krem B4), Sharon Hennessy and Jean-Pierre Bartholeyns rigged and surveyed most of entrance pitches. According to Brown et al. (2008 Mss: 'Meghalaya 2008 diary' Thursday 7th February), Robin, Sharon and Jean-Pierre went to B-4 (now Krem Lumthymme). They surveyed down through the boulder choke and rigged down a series of shafts (c60 m depth) to a stream-way, still going. 2008.02.08, trip 3: R F Sheen (2008.02.08 Mss: Krem B4), Sharon Hennessy and Jean-Pierre Bartholeyns finished rigging pitches and continued surveying to nearly canals.According to Brown et al. (2008 Mss: 'Meghalaya 2008 diary' Fiday 8th February), Robin, Sharon and Jean-Pierre continued to rig and survey Krem Lumthymme. Having dropped the final pitch they went down a large passage with pools containing fish and shrimp. This led to a section of chest-deep canals and a boulder squeeze c.160 m surveyed. 2008.02.15, trip 4: Jeff, Ross and Robin went to B4. After surveying small canals in waist deep water they broke through into large well decorated fossil passage, which was surveyed for about 200 m, with no sign of stopping (Brown et al. 2008 Mss: 'Meghalaya 2008 diary' Friday 15th February). 2008.02.16, trip 5: Jeff, Ross and Robin went back to B4, where they continued exploring the upstream, high level passage to a terminal choke. They inspected a choke downstream, which looked promising (Brown et al. 2008 Mss: 'Meghalaya 2008 diary' Saturday 16th February). 2008.02.17, trip 6: Jeff, Ross and Philippa went to B4 and finished off the surveying (Brown et al. 2008 Mss: 'Meghalaya 2008 diary' Sunday 17h February). 2008.02.18, trip 7: Jeff and Philippa derigged Krem Luthymme (Brown et al. 2008 Mss: 'Meghalaya 2008 diary' Monday 18th February).
