The massive mountains seem to bend around a pivotal point on both the ends. The westernmost point is located where the Hindu Kush joins the Karakoram south of the Pamir. Arunachal Pradesh’s eastern border features a similarly abrupt, almost hairpin curve when the mountain’s strike abruptly shifts from an easterly to a southerly tendency.

The northern region of Gujarat comprises the Kutch and Banaskantha districts, which are characterized by arid and semi-arid conditions due to low annual rainfall (less than 500 mm).

Gujarat is highly commercialized in agriculture, focusing on cotton, groundnut, tobacco, and castor rather than food crops. The Saurashtra and Kutch regions specialize in cash crops due to their soil type and climatic conditions.
