On the western side of the Huron River above the Lake Shore 
& Michigan Southern Ry. bridge in Monroeville is a to— ft.+ 
bank composed mainly of black shale, but with a little blue shale. 
The upper part of the bank overlying the black shale shows zones 
of blue- to olive-colored shale, perhaps 6 in. thick, alternating with 
black shale. Toward the lower end of the bank are numerous 
rather irregular to lenticular-shaped concretions a little above river 
level and a little farther up stream similar concretions occur in its 
bed. This is apparently the continuation of the lower portion of 
the Needham section; although its stratigraphic position was not 
determined as accurately as might be desired. The base of the 
section is vertically probably not more than 8 ft. above the top of 
the rocks studied below the dam. 
One-fourth mile farther up the river and a little below the house 
of William Schug is a shale bank from 27 (hand-level) to 30 
(barometer) ft. high.
