The Port Orford Formation is a geologic formation in Oregon.
[citation needed] It consists of beds lying unconformably between the Empire Formation and overlying terrace deposits.
[1] The formation is composed of a basal bed of buff (yellow-brown) sand, overlain by a layer of conglomerate, and layer of rusty sand grading upward into blue-gray argillaceous sand, which is then truncated by the sea, on top of which are the Elk River Beds.
[1] The name was proposed by Ewart M. Baldwin in 1945.
