Tham Nam Dan - NA0045
19.418510,101.062508
Location
From the Security Development Project take the road south into the doline. Before the bend to the left take a track on the right which contours round, past two small depressions and through an orchard to drop down onto the floor of the doline. Cross the doline and look for a large boulder at the edge of the field. An indistinct path goes up the slope to the right of the boulder for about 30 m ascent to the entrance at the foot of the cliff.
Description
Tham Nam Dan is a steeply descending (45¦) boulder floored passage which is 15m to 20m wide. Unfortunately after 100m the passage becomes choked with boulders and earth. Although a draught was noticed between the boulders at the end of the cave all ways on were very small.
