The Gable Creek Formation is a sedimentary rock formation from the Albian age of the Early Cretaceous. ^[1] The formation is in Wheeler County, Oregon of the United States of America and is intertongued with the similarly aged Hudspeth Formation. The formation mostly consists of fluvial-deltaic sandstones and conglomerates. ^[2] Marine fossils can be found throughout the formation including various species of ammonites, clams and other mollusks. The Gable Creek Formation gets its name from Gable Creek, a creek that runs through much of the formation.
