Rageh Valley, like many other valleys in Iran, has been created due to water erosion. There is a seasonal river in the depths of this valley, which over time has washed away the soil and rocks and its emergence.
Tang-e Boraq (Boraq Gorge) is another erosive gorge in the north of Fars province, which is located about 160 km from Shiraz and near a village of the same name.
Khazineا Valley is located on the border of Lorestan and Ilam provinces. This valley is located right next to the main road from Andimishek to Pol Dokhtar.
