Khyber Pakhtunkhwa sits primarily on the Iranian plateau and comprises the junction where the slopes of the Hindu Kush mountains on the Eurasian plate give way to the Indus-watered hills approaching South Asia. This situation has led to seismic activity in the past. The famous Khyber Pass links the province to Afghanistan, while the Kohalla Bridge in Circle Bakote Abbottabad is a major crossing point over the Jhelum River in the east.
