Al Naslaa
The Al Naslaa rock is a landform 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. 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. 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.
