Kaluts are natural features that occur due to environmental erosion in sedimentary mountains or hills of desert areas. This erosion can be due to wind or due to rain and running water in the riverbed.
By passing through the village of Mesr to the north and walking about 3 km between the groves and farms of the village of Mesr, the last settlement of the desert in this area, Farahzad village, can be reached.
The city of Varzaneh, with several natural and ancient monuments together, has become an important destination for domestic and even foreign tourists in recent years.
At the end of the road that connects Mesr to Farahzad, there is a large hole with a different view. A large pit known to the locals as the Chal Selkanun (Selkanun pit).
