The Jalama Formation is a sedimentary rock formation widespread in southern Santa Barbara County and northern Ventura County, southern California. Of the Late Cretaceous epoch, the unit consists predominantly of clay shale with some beds of sandstone.
A particularly erosion-resistant sandstone within the unit forms the scenic Nojoqui Falls, in the Santa Ynez Mountains south of Solvang.
