The Khirthar range consists of an ascending series of ridges, running generally north to south with broad, flat valleys in between. These ridges are locally distinguished by different names, for example, the first line of hills is known as “Kakrio” (broken), the next as “Karo”(Black), and the third as “Pinaro” (Saffron coloured). The highest ridge of the range at its northern extremity is about 1,500 meters above the sea-level. The most elevated peak known as “Kute-ji-Kabar” (dog's tomb) is 2064 meters above the sea-level.
