Location: Blowing Cave is located in the Blowing Cave Georgia Militia District, in northwest Grady County, Georgia. It is about two miles west of the Hawthorne Trail, Ga. Hwy. 112 and about 8 to 9 miles northwest of Cairo, the county seat. It is just west of Mizpah Baptist Church, which is located just west of Hawthorne Trail near the Grady County - Mitchell County boundary.
Geology: Blowing Cave is located near the eastern rim of the Flint River valley. Topsoil here lies above a thick layer of limestone rock dated to the period between the Oligocene and Miocene epochs. That means the limestone in this area was created between 7 million and 16 million years ago, very young in Earth's age.
