Also known as D -1076

Where: Frensno County, California (36.3° N, 120.4° W: paleocoordinates 35.6° N, 116.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Temblor Formation, Middle Miocene (16.0 - 11.6 Ma)

• From the lowest three sandstone ledges cropping out on hill. Each ledge is approx. 2.5 feet thick and separated from others by variable intervals of silty sandstone. Total thickness of around 30 ft. From faunizone B (zone 3) (for that reason assigned an middle Miocene age).
