The first Harappan flint quarries here were discovered during a preliminary survey carried out in January 1986 by the writer and Prof. M. Cremaschi of Milan University (standing close to one of the structures). They are in the central-western part of the hills, near the shrine of Shadee Shaheed (map)..
The quarries are so well preserved because environmental conditions have not changed. Nobody has touched them for 5,000 years. Quarry pit have also been buried under wind-blown sand.
