Tham Huai Tong Thai - KA0413
15.216234,98.903509
Location
Located in boulder field at the junction of the Huai Tong Thai and Nam Mae Chon (Mae Khlong) rivers in Thungyai Naresun West Wildlife Sanctuary.
Description
The entrance is 25 m above the resurgence. This opens into a small dry upper chamber with a way through at the back leading to an 8 m drop to the river passage. The river passage averages 5 m wide and 10 m high. The rock is very sharp and brittle, fracturing easily making climbing over boulders hazardous and dangerous. At the first boulder fall a way over was found on the right hand side. After 500 m of large river passage a very large boulder chamber was encountered which is about 80 m wide by 30 m high. A steep 20-30 m scrabble on a very loose and dangerous slope up the left-hand side ended in a hazardous 3 m vertical climb before topping out. On the top of the boulders were three large standing stalagmites (approximately 5-6 m tall and 2 m in diameter) along with others that had fallen over. The main river passage continues for a further 1 km before exploration was stopped by a large boulder choke which could not be passed. Main sink is 3 km away and 225 m higher and other possible sinks 7 km away and 500 m higher.
