Where the strike is weathered it has a peculiar rusty brown appearance which is very characteristic of the Clinton in Lincoln Co. [23]- 7 A little over a mile south eastward, just far beyond Hale's Well, the base of the Black Shale is seen at 1075. Six feet below contain no exposure. Below this is typical Madison rock. [239]- 8 Half a mile eastward and then half a mile southward in the Halls Gap road, the Black Shale stone base is seen at 1110 south of the black. with clays, and right of the same the Clinton is yet at the road side, but there is no contact. [240]- 9 About a mile south of Hale's Gap Station, the Black Shale base is seen at 1125. About 10 feet of rock below the shale are too decayed to be rec- gognized but below this line is undulated Madi- som. [24]- 10 On a road turning of eastward, the base of the Black Shale is at 1140, [242]- 11 Being a mile eastward in the last mentioned road, and then nearly a mile southward, the base of the Black Shale is seen at 1125. The Clinton di- rectly beneath is here 15 feet thick, and rests on the clays Madison. The Clinton is quite curr- due although the stone has laments are of smaller size. The increased thickness indicates less error in eastward, not increased deposition. 147
