Many sites were discovered across northwestern India.
Between 19, more than 50 sites were excavated in the Kutch (notably Dholavira), and Saurashtra peninsulas, extending the limits of Harappan civilisation by 500 kilometres (310 miles) to the river Kim, where the Bhagatrav site accesses the valley of the rivers Narmada and Tapti.
To the northwest of Lothal lies the Kutch (see also Dholavira) peninsula, which was a part of the Arabian Sea until very recently in history.
Owing to this, and the proximity of the Gulf of Khambhat, Lothal's river provided direct access to sea routes.
Its constant threats - tropical storms and floods - caused immense destruction, which destabilised the culture and ultimately caused its end.
Topographical analysis also shows signs that at about the time of its demise, the region suffered from aridity or weakened monsoon rainfall.
Upstream elements of this river provided a suitable source of freshwater for the inhabitants. 3000 BCE), Lothal was a small village next to the river providing access to the mainland from the Gulf of Khambhat.
The indigenous people maintained a prosperous economy, attested by the discovery of copper objects, beads and semi-precious stones.
The beads and gems of Lothal were in great demand in the west.Thus the cause for the abandonment of the city may have been changes in the climate as well as natural disasters, as suggested by environmental magnetic records.Lothal is based upon a mound that was a salt marsh inundated by tide.Lothal stands 670 kilometers (420 miles) from Mohenjo-daro, which is in Sindh.The meaning of Lothal (a combination of Loth and (s) thal) in Gujarati to be "the mound of the dead" is not unusual, as the name of the city of Mohenjo-daro in Sindhi means the same.
People in villages neighbouring to Lothal had known of the presence of an ancient town and human remains.
