80 GEOLOGICAL SURVEY OF ALABAMA. 



has been cut at so many places, and at different levels, that 

 it seems probable splitting of some of the beds has occurred. 

 The Clinton ridge becomes gradually lower toward the S. 

 W. side of Section 7, but continues to carry large amounts 

 of iron ores. There is probably more iron ore in the mile 

 and a half just passed over than in any equal length of the 

 Clinton on this side of the valley. 



South-west of the 1st principal meridian line, in S. 13, 

 T. 14, R. 1 W., the Clinton ridge sinks still lower until its 

 top is almost on a level with the floor of the valley, and so 

 continues mainly into S. 24. Very little ore is found along 

 this sunken portion ; yet it may exist beneath the water 

 level. In the corner of S. 24 a bed of iron ore was seen 

 nearly 3 feet thick, but rather inferior in quality. It occurs 

 in large coarse blocks, like carbonate ore, and its position in 

 the Clinton was not apparent. 



On the lands of Green Posey in S. 24, T. 14, R. 1 W., is 

 found a large deposit, or ledge of the Lower Siliceous, or 

 Keokuk Limestone. It is probably as large and thick as the 

 one at the Wade Gap in S. 27, T. 13, R. 1 E., but not gen- 

 erally of as good quality, though it contains much very pure 

 lime rock. In the face of this limestone bluff a deep cave 

 extends rapidly downwards. It evidently carries off the 

 waters of the branch which sinks near its mouth it may be 

 an extensive one, but is not known to have been explored. 



South and East of this cave and limestone bluff, and from 

 fifty to one hundred yards distant, the Lagrange or Oxmoor, 

 Sandstone makes a prominent ridge, with rocks standing 

 almost vertical, and some of them of imposing height. This 

 place is about half a mile South of Remlap Station on the 

 Birmingham Mineral R. R. 



From near Remlap to Mt. Pinson, or Turkey Creek, the 

 Sparry or Cambrian Limestone is not exposed. The Lower 

 Silurian Chert adjoins, and often laps over on the Clinton. 

 In this portion of the valley the depth of the break, and the 

 amount of displacement of strata by the great fault is, 

 lessened by 500 to 1000 feet. 



South-west from Remlap about a mile, in S. 23, T. 14, R.
