WAVERLY SERIES OF CENTRAL OHIO 227 



To the east of the Hanover railroad station is a cut in which 

 the contact of the Black Hand conglomerate and overlying 

 Logan sandstone is nicely shown. To the south of the cut and 

 highway is the quarry of the Hanover Pressed Brick Co. in the 

 shales of the Logan formation. The section from the railroad 

 to the top of the quarry is as follows : 



Thickness Total thickness 

 feet feet 



No. 4. Mainly blue to drab argillaceous shales with 

 some bands of sandstones which vary from 

 7 inches to perhaps a foot in thickness - 20 92 



3. Covered ... - 18 72 



2. Buff shaly thin bedded sandstones containing 

 fossils which are well shown in the upper part 

 of the railroad cut in the vicinity of the high- 

 way bridge. Lower part of the Logan sand- 

 stone which is separated by quite a sharp line 

 from the massive grit to conglomerate below. 

 There are some thin layers of conglomerate 

 near the base of the Logan sandstone. 22 54 



1 . Massive grit to conglomerate which forms the 

 lower portion of the cut. Part of the rock is 

 a buff grit and the remainder a conglomerate 

 some of the pebbles of which are quite large. 32 32 



BLACK HAND CONGLOMERATE 



The Black Hand conglomerate named from the cliffs in the 

 gorge of the Licking River, known as the Licking Narrows, 

 begins a short distance above the station of Black Hand on the 

 Baltimore and Ohio Railroad. 1 On the north side of the river 

 rather more than a quarter of a mile above the bridge are two 

 conspicuous cliffs, the lower one called Red Rock and the upper 

 one Black Hand which is shown in Fig. 4. On the southern 

 side of the river is a railroad cut which shows finely the contact 

 of the Black Hand conglomerate and the Logan sandstone. To 

 the west of the cut at a distance of about one half mile from the 

 station is a prominent cliff in one part of which is the E. H.
