The 'Karewa' formations, known for being extremely fertile for saffron cultivation, are thick deposits of glacial clay and silt found primarily in which region?

💡 Solution & Explanation

Karewas are specialized lacustrine deposits found extensively in the Kashmir Valley, providing fertile soil conditions essential for the commercial cultivation of saffron. Other Himalayan valleys like Kangra or Chamba lack these specific glacial-lake sediment structures and their associated cash crops.
