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-central 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.
