Mor Ja Bok Potholes
There is a wide area of rock approximately 1,000 square meters in size at Hoeb Hill that lower slopes to the south until Sap Pradu reservoir with more than 100 depressions in the shape of pot or potholes. The potholes have diameters ranging from 100 to 250 centimeters and they range from shallow to a depth of approximately 2 meters. These potholes provide evidence of a former stream with flowing water with swirling water currents that swept in fragments of rock. These fragments abraded the rock surface of the sandstone down to varying depths. Later, the rock layer uplifted and the stream changed the direction of flow until the potholes became exposed as a present.
