Summary:

Bicknell sandstone of Diller (1892) is adopted. Chiefly red and gray sandstone associated with some dark shales and tuffaceous beds. Brownish-red sandstone forms earliest part of formation. Middle part is compact, fine, dark-gray sandstone interbedded with black shaly beds. Upper part consists of tuffaceous gray sandstone. Thickness 500 to 1,300 feet. Overlies, probably conformably, Mormon sandstone and grades into overlying Hinchman sandstone. Age is Late Jurassic.
Greatest development on southeastern slope of Mount Jura, Plumas Co., Taylorsville region, northern CA.
