Summary:

Moody shale member of Toledo formation. Dark to black hard tuffaceous mudstones, commonly intricately fractured, with occasional discontinuous, irregular, hard cemented limy bands a few inches thick; interbedded fine- and medium-grained sandstones containing glauconite and coarse pumiceous material occur at numerous horizons; carbonaceous material and plant fragments abundant in sandstones near base. Thickness 1,500 to 1,800 feet. Along Eckman Creek and south of Green Mountain, member becomes markedly tuffaceous and interfingers with volcanic rocks of the Toledo to the south. Underlies an unnamed sandy member 1,000 to 1,200 feet thick; overlies Burpee formation. Age is late Eocene. (Moody shale member of Toledo formation adopted by the USGS.)
Type locality: at Moody School, north bank of Yaquina River in sec. 30, T. 11 S., R. 10 W., Lincoln Co., northwestern OR.
