658 WILBUR GREELEY BURROUGHS 



Therefore the Ohio quarry is located in a depression of the eroded 

 horizon of the Bedford shale. The Ohio pit is 175 feet wide, yet 

 neither bank of the Bedford channel in the quarry has been reached. 



By drill and well records, the writer has traced this channel, in 

 which is the Ohio quarry, for a distance of three and one-half miles 

 to the southwestward where it outcrops on the steep valley slopes 

 of a stream known as Chance Creek. Here the lens of sandstone 

 is 50 feet wide and 15 feet thick. On both sides and at the bottom 

 the sandstone lies directly against the red Bedford shale. The 

 decreasing of the channel in depth and width as it went south- 

 westward indicates that the stream flowed from the southwest 

 toward the east. 



Beaver Creek flows a little less than one-half mile east of the 

 Malone quarry. Here no sandstone is found along the banks, in 

 spite of the fact that the axis of the anticline is plunging in that 

 direction at an angle of 3 . The outcrops of Bedford shale at this 

 place on the creek are 30 to 40 feet lower in elevation than the top 

 of the sandstone at the Malone quarry, where the sandstone is 100 

 feet thick. Still, if the Malone quarry deposit of Berea grit is not 

 a sandstone-filled depression in the Bedford shale, the sandstone 

 should outcrop at Beaver Creek, which it does not do. This quarry 

 therefore also is located in a lens of sandstone in the horizon of the 

 Bedford shale. 



A short distance farther north of the Malone quarry is No. 6 

 quarry of the Cleveland Stone Company. Structurally this quarry 

 is on the southward-dipping flank of an anticline whose axis runs 

 in a southwesterly direction. The average dip is 8°. The axis 

 itself is folded into a low, small anticline in the west portion of the 

 quarry. Here, as elsewhere in the region, the sudden great thick- 

 ness of sandstone cannot be accounted for save as a sand-filled 

 channel of the eroded horizon of the Bedford shale. Although the 

 long axis of No. 6 quarry does not exactly coincide with the direc- 

 tion of the channel in which it is located, yet, both being in nearly 

 the same westerly direction, the size of the pit gives some idea as 

 to the size of the valley in the Bedford formation. The quarry is 

 2,632 feet long, has an average width of 460 feet, and a depth of 

 from 100 to 175 feet.
