Bir al-Qurr

Bir al-Qurr lies in the rocky country southwest of Hala al-Badr, a volcanic cone in northwestern Arabia. The cone stands at the edge of Jabal Thadra, a table mountain of sandstone capped by basalt. Below it lies al-Jaww, a broad eroded basin between the lava fields of Harrat ar-Rahah and Harrat al-Uwayrid. Ancient lava spread across parts of this basin.
