Location
This shaft is in the central part of Doi Luang Chiang Dao, in the valley between the two ridges. It opens at the bottom of a doline filled with vegetation.
Description
The entrance is a 19 m pitch, followed by a few short drops. There is then a 16 m pitch to a horizontal meander at -55 m. This rift takes a stream, but appears to be too tight in the downstream direction. Upstream the water enters via a 10 m waterfall.
