Notes on the Tham Luang survey หมายเหตุในการสำรวจถ้ำหลวง

 
It must be stressed that the Tham Luang survey is very inaccurate and cannot be used, on its own, to select drilling targets.
On the landscape scale it looks OK – Monk's Series heads towards Pha Mi, main cave follows the spine of the mountain, avens and low wet section as the southern end of the cave passes under the gorge – but the error radius for a station at the end of the cave could be hundreds of metres.
