Al Naslaa
The Al Naslaa rock is a landform 50 km south of the Tayma oasis in Saudi Arabia. It is split down the middle into two parts, both balanced on small pedestals. The overall shape of the rock may be due to wind erosion and chemical weathering that could have been possible due to the moist conditions in the protected underside of the rock. It is split in two by what could be a joint. The rock is about 6 metres high and 9 metres wide, and is covered on its south-east face with numerous petroglyphs. References
