Paranabuku

Paranabuku lies in the dry interior north of the São Francisco, near the basin of the Pontal River. The Pontal drains country between Dormentes and Lagoa Grande towards the great river, while the neighbouring Garças basin lies to its north. In this part of Pernambuco, small watercourses cross the thorny vegetation of the caatinga and change greatly with the rains.

The later city of Petrolina lies here.
