Tham Khun Nam Ru - CM0127

Martin Ellis - 27/06/2019

A partially boulder-choked rift entrance leads down into a sizeable chamber 20 m across. The rear wall of the chamber is composed entirely of stalagmite, in which a small eyehole opens out into a second chamber. However, this was too tight to pass, but a large deep pool could be seen beyond and the cave was seen to curve away out of sight. A slight draught was detectable blowing out. The cave is a high level fossil outlet to the major conduit which resurges at Khun Nam Ru. If the eyehole was enlarged more passage might be gained together with a very promising dive site.
