Location
This cave is at the upstream end of the doline with the Tham Mae Lana swallet entrance. The entrance is in a a small doline 500 m north of the Tham Mae Lana sink.
Description
The cave gives access both to the main Mae Lana underground river and a seasonally active tributary. The former encounters a sump after a short distance, which presumably connects with the downstream sump in Tham Pakarang. The tributary can be followed upstream to the north-west with increasing difficulty for over a kilometre and appears to drain the area near Ban Chabo. Spies (2000) described it as "Upstream Mae Lana" including Tham Nam Tok. entrance to main upstream sump = 230 m Tributary to boulder choke = 978 m Upper chamber in Tributary = 37 m Oxbows in tributary = 160 m
