The mapped area lies in theo southern end of the Coos Bay coal field. Coal occurs onle in the upper and lower members of the Coaledo Formation. Nearly all the coal mined in the Coos Bay coal field was from the upper member of the Coaledo Formation. In the mapped area, most of this member has been eroded; only a few hundred feed of the basal strata remains. Allen and Baldwin (1944, p. 131, 116) reported 2 feet 7 inches of coal and bone along Hall creek in the NW1/4NW1/4 sec. 11, T. 29 S., R. 13 W., and 4 feet of coal and bony coal at the Albee prospect near the center of the NE1/4 sec. 4 T. 29 S., 13 W.
