The formation consists of a massive cobble conglomerate with a dark yellowish-brown coarse-grained sandstone matrix.[1] The conglomerate has dispersed lenses of fossiliferous crossbedded sandstone.[1]

It overlies the Friars Formation, and underlies the sandstone Mission Valley Formation.[1]

Fossils

It preserves fossils dating back to the Eocene epoch of the Paleogene period, during the Cenozoic Era.[3] The fossils include calcareous nannoplankton.[1]
