In India, glacial terraces known as ‘Karewas’ are found in

Karewas are unique lacustrine (lake) deposits found in the Kashmir Valley, specifically within the Jhelum Valley [1]. These formations consist of thick layers of sand, clay, silt, and bouldery gravel that date back to the Pleistocene period [2]. Geologically, they were formed when the entire Kashmir Valley was submerged under a vast lake due to the upliftment of the Pir Panjal range; the lake eventually drained through the Baramulla Gorge, leaving behind these elevated tablelands or terraces [3]. These terraces are found along the flanks of the Pir Panjal and border the Jhelum river [3]. Karewas are highly significant for agriculture, particularly for the cultivation of saffron (Zafran), as well as orchards for almonds and walnuts [1]. They are distinct from the river systems of the Sapt Kosi, Alakananda, or Teesta valleys.
