The bay was formed in a 13 km wide impact crater. The age of the crater is estimated to be 99 ± 4 million years (Cretaceous).^[3]

The smaller Gow crater, of Triassic age, is approximately 90 km west of Deep Bay crater. The Carswell impact structure, also of Cretaceous age, is to the northwest of Deep Bay and Gow.
