Location

The various entrances to this cave are located 7 km east of the H1095 and 1.5 km west of the Mae Nam Khlong river. From Ban Mae Suriya the track to the Susa Waterfall has recently been upgraded and from the waterfall it is a 1.75 km walk south beside the Mae Nam Khlong before turning west and following the Huai Pba Teung upstream for 1 km to the cave. Tham Huai Pba Teung is at the head of the main tributary stream, while the 3 m diameter entrance to Tham Lom lies behind a pool a few hundred metres downstream from Tham Huai Pba Teung. The Tham Sua Upper and Lower entrances are between Tham Huai Pha Tung and Tham Lom, being a short distance above and 100 m south-west of Tham Huai Pha Tung. Martin Ellis - 08/05/2020

Description

Martin Ellis - 08/05/2020

The Tham Sua/Tham Lom system is a complex of caves that collect the water from two streams which are about 1km apart and are both called Huai Kut Pa Tung. The streams sink in dolines, each containing a cave (MH219 'pothole' and Tham Huai Kut Pa Tung). The Tham Sua/Tham Lom system has four entrances: Tham Huai Nam Tung, Tham Lom and the Tham Sua Upper and Lower Entrances. The relationships between the passages in the system are unclear. Tham Huai Nam Tung appears to lie within a high hill at least 500m south of, and trending away, from from the Tham Huai Kut Pa Thung doline and so may once have carried drainage from the MH219 pothole. In Tham Huai Nam Tung the cave starts as a crawl under and through rocks which leads to a chest deep wade. About 100m from the entrance the stream enters on the left side from a low passage that has not been fully pushed. The main, now dry, open walking passage can be followed west and south-west, rising gradually. After about 600m Bat Passage can be followed north-west for 200m to a sump. A short distance further on a narrow canyon, leading to 100m of muddy crawls, has not been fully explored. The passage gradually turns to the east along the Maekhong Way and after 500m a junction leads after 300m to the Tham Sua entrances. After a further 200m and 350m there are two seperate pitches, a P20 and a P25, which connect to Tham Lom. The passage is seen to continue beyond the P25, but has not been explored. At Tham Lom the 3m diameter entrance gives access to an attractive sporting cave which is characterized by phreatic tube passages 3-4m in diameter. The Tham Sua Upper and Lower entrances join via a 10m pitch just inside the cave. From the upper level a very muddy, walking-sized passage, which has not yet been explored, heads towards the low inlet near the entrance in Tham Huai Nam Tung. The lower level trends south-west along some attractively decorated passage, connecting after 300m with Tham Huai Nam Tung.

History

After the initial exploration of Tham Huai Nam Tung and Tham Lom by the 1985 and 1990 Australian expeditions, in 1993 a team led by Dean Smart surveyed 2,886 m in the system, with another 300 m known from earlier. Martin Ellis - 08/05/2020
