Over time, as languages evolved and adapted, "giri" transformed into "gir" in Gujarati and further into "kir" in Sindhi.

The term "thar" signifies the desert-like characteristics of the region, marked by its dry climate and sparse vegetation.

The mountains extend southward for about 190 mi (310 km) from the Mula River in east-central Balochistan to Cape Monze on the Arabian Sea.

The next highest peak is the 6,880-foot-tall (2,100 m) mountain Kutte-Ji-Kabar (Sindhi for "Dog's Grave"), also known as Kuchak-na-Kabar in Brahui.

[7] As recorded in Folk Tales of Scinde and Guzerat (circa 1855),[5] the mountain is named for a story in which a Brahui man is forced to leave his dog as collateral to a wealthy Hindu merchant in order to settle his debts.

[10] There are also a number of other peaks of the Kirthar Mountains exceeding 5,500 ft (1,700 m), which all receive occasional snowfall during the winter season.

The Kirthars are part of the Kirthar-Sulaiman geologic province,[2] which stretches from the Arabian Sea coast north to northwestern Pakistan along the western boundary of the Indus Valley.

[13] Major tribes living in the Kirthar are Chhutta, Burfat, Gabol, Marri, Bozdar, Lund, Nohani, Bugti, Chandio, and Lashari.
