THE KASHMIR valley owes much of its fortune to the plateau-like landforms that remain tucked away in the folds of the surrounding mountains, particularly the Pir Panjal range of the Himalayas that borders the valley on the southwest. Known as karewa, these plateaus are 13,00018,000 m-thick deposits of alluvial soil and sediments like sandstone and mudstone. This makes them ideal for cultivation of saffron, almonds, apples and several other cash crops. Kashmir saffron, which received a Geographical Indication (GI) tag in 2020 for its longer and thicker stigmas, deep-red colour, high aroma and bitter flavour, is grown on these karewas.
The fertility of these patches is believed to be the result of their long history of formation. When formed during the Pleistocene period (2.6 million years to 11,700 years ago), the Pir Panjal range blocked the natural drainage in the region and formed a lake spanning 5,000 sq km (roughly three times the size of Delhi). Over the next few centuries, the water receded, making way for the valley and the formation of the karewas between the mountains. Today, the karewa sediments not only hold fossils and remnants of many human civilisations and habitations, but are also the most fertile spots in the valley.
