Overlook spans an 8-mile gorge with towering limestone walls and the Rio Grande threading the bottom. The carving force is river-driven downcutting through Lower Cretaceous limestone, aided by uplift along the Terlingua Fault as the land rose yet the river stayed on its channel. The exposed rocks record a Cretaceous interior seaway, offering a deep geologic perspective at the border.
