Also known as CAS loc. 69275

Where: Lake County, California (38.9° N, 122.5° W)

• Paleocoordinates: 38.1° N, 57.4° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: Blue Ridge Member (Crack Canyon Formation), Valanginian (137.1 - 132.6 Ma)

• This area has been mapped as Valanginian (Lower Cretaceous) as part of the Blue Ridge member, comprising the lower member of the Crack Canyon formation (informal name of Lawton 1956), Great Valley Group. However, the extent and complexity of the bedding−plane faults in this area, with the resultingunconformities, was not fully appreciated in Lawton's time, andmany of the age assignments are based on inferences that requirefurther structural and stratigraphic evaluation (Dean A. Enderlin, personal communication, 2004).
