The Al Naslaa rock is a landform 50km (30miles) south of the Tayma oasis in Saudi Arabia. It is a large sandstone rock split neatly down the middle into two parts, both balanced on small pedestals.[1] The overall shape of the rock is due to wind erosion and the chemical weathering made possible by the moist conditions in the protected underside of the rock.[2] It is split in two by a joint.
The rock is about high and wide, and is covered on its south-east face with numerous petroglyphs.[3]
