It is in the Phu Phan rock unit, Korat series, in the lower - mid-Cretaceous period, or about 90-140 million years ago. The sandstone in the area has outstanding geological features. Because there are different properties in each floor. and has undergone geological erosion by water and wind. Makes the appearance of the landscape that is strange in many areas, such as Hor Nang Usa, Tham Chang, Father Ta's coffin, Thao Baros coffin, Nang Usa coffin, Pho Ta temple, Phra Ku Nang Usa cave, Nang Usa pond. Quail Stone Shed as well as the geological, physical and geological features found in the sandstone. which is a clear stratum or sedimentary rock For example, showing interleaving layers with gravel layers. An oblique-level display showing a change in water flow direction. (Department of Mineral Resources 2009 :38-39)

various shapes formed from sandstone and gravel sand have different texture The highly durable rock layers protrude into rock sheds. or a layer of rock overlaid on top The less durable rock layers will erode. or being eroded or is a concave part under the hard rock Become a rock shed or a rocky cliff such as Hor Nang Usa, etc.

The condition of the source is a large rock shed consisting of boulders measuring 3 meters wide, 8 meters long, 1.8 meters high from the ground, stacked on a hollow rock core. (62) Inside the rock shed and the rock cavity that formed the rock formed the appearance of the rooms that are connected within the stone sheds of 2 rooms with the entrance to the stone sheds to the north In addition, in front of the stone shed on the south side, a 25 cm hole was extracted.

Archaeological evidence has been extracted into two 20-centimeter diameter holes in the innermost corner of the chamber and a hole in front of the entrance of the stone shed. Diameter 30 cm. (Pitachai Chatuchai 2010 :61-62)

In the past, not so long ago Villagers used to use the hunter's rice barn as a place to trap animals. and said that paddy was found in this rock shelter, so it was called Chang Khao Nai Pran.

Pitakchai Chatuchai (2010 :63) assumed that from the nature of the source that is a large rock shed and hollow inside which can be used as a shelter from the sun as well Therefore, it is suitable for use as a residence. And the pits resulting from the ground extraction are traces that show their use as a residence or residence of monks in the historical Dvaravati and later periods.
