Geography & Plateau
Jharkhand GK · भूगोल और पठार
📋Quick Overview
Jharkhand lies entirely on the Chota Nagpur Plateau, which is part of the ancient Deccan Plateau and one of the oldest geological formations in the world. The plateau rises steeply in the west and slopes gently towards the east and northeast. The highest peak in Jharkhand is Parasnath (1365 m) in Giridih district — a sacred Jain pilgrimage site. The Damodar river, called Jharkhand's 'Sorrow' due to devastating floods, drains westward. The Tilaiya Dam on the Barakar river was India's first multipurpose dam (1953).
Parasnath Hill (1365 m) = highest peak of Jharkhand; sacred Jain pilgrimage; 20 Jain Tirthankaras attained moksha here
Tilaiya Dam (1953) = India's FIRST multipurpose dam; built on Barakar river (tributary of Damodar); Damodar Valley Corporation (DVC)
