Summary:

Named as formation (of 6) in La Jolla Group for exposures along sea cliff north of Scripps Institution of Oceanography. Type section is on north side of mouth of Blacks Canyon about 1 km north of pier at Scripps Institution, San Diego Co, CA. Rocks have previously been included as part of Hanna's (1926) Rose Canyon Shale Member of former La Jolla Formation. Consists of pale-yellowish-brown medium-grained sandstone, containing in lower two-thirds three cobble-conglomerate beds. Is 67 m thick at type. Conformably overlies Ardath Shale (new) and in places Torrey Sandstone (both of La Jolla Group). Conformably underlies Friars Formation (new) of La Jolla Group. Age is middle and late Eocene based on molluscan fossils.
