Tham Urai Thong

Tham Urai Thong is a cross limestone cave in an isolated north-south elongated cliff mountain about 40 meters long and 25 meters wide. There are three caves in the mountain but the Urai Cave is the largest with both stream inlet and outlet at the eastern and western sides respectively. A joint system can be observed that might be the ways the cave has been developed. The south wall of the cave reveals three sea notches suggesting that the cave was affected by the sea incursions as well as the presence of some sea mollusk shells on the cave floor such as Anadara spp., Polymesoda proxima, Nerita spp. and oysters. The mollusk shells are mostly in the upside positions. There are some ancient human and animal bones found in the cave including rhinos, zebras, bovines, and boars. The animal bones are generally fragmentary pieces suggesting that they might bemade by the ancient humans.\r\n
