LACMIP 5802 Bear Creek (Eocene of the United States)

Also known as UWBM B-7443

Where: Pacific County, Washington (46.3° N, 123.9° W: paleocoordinates 46.7° N, 111.6° W)

• coordinate stated in text

When: Priabonian (38.0 - 33.9 Ma)

• In 1954, during the last active quarrying, the limestone was reported as 15 m thick, 68 m in length, and 38 m wide (Danner, 1966). Informal "siltstone of Cliff Point" (Wells, 1989). Age: late Eocene (calcareous nannofossil CP 15b Zone of Okada and Bukry (1980) and benthic foraminiferal Refugian Stage (Goedert and Squires, 1990); temporal equivalent to the lower part of Lincoln Creek Formation. Age confirmed with Nesbitt 2018.
