These formations in the Pothohar Plateau date back to 600-540 million years ago. Over time, these strata and the succeeding Cambrian to Eocene sedimentary rocks were pushed southward and eroded, forming the Salt Range. The highest peak in this range is Sakaser, standing at 1522 m. Commercial salt mining has been ongoing here since at least the 16th century, with active salt mines in Khewra, Warcha, Kalabagh, and Jatta.
