Situated at 155 meters above sea level, with its scenic splendours Pasighat is Arunachal's oldest town and also the district headquarters of East siang ditrict. HISTORY:
Pasighat was founded in 1911 A.D. by the Britishers as a gateway to administrative convenience of the greater Abor Hills and area north. GEOGRAPHY:
The place is known for receiving highest rainfall in a single year. In fact Pasigh
at and area around it receive heavy rainfall every year during monsoon season starting from May till September. The unique trough like features surrounded by high hills on all three sides make this place ideal for attracting rain bearing cloud which comes in from Assam plain. The rain bearing wind gets obstructed by the hills and brings heavy downpour. Winter is marked by cold dry local seasonal wind which blows throughout the winter. This factor contributes in making this place fog free even in winter. Bhramaputra emerges from the foothills under the name of Dihang or Siang. It enters India as Dihang west of Sadiya town in Arunachal Pradesh.Flowing southwest, it receives its main left bank tributaries, viz., Dibang and Lohit; thereafter, it is known as the Brahmaputra.
