At Ba Kelalan,the head of Trusan,there are several salt wells.The salt water is dipped out of the well and carried in lengths of bamboo to a shed where the water is boiled away in a large pots.Formerly,when access to the coast was difficult and dangerous,such salt wells were an important economic asset and the salt was traded over a wide area.The people there mostly are from Murut people.
