Rh Kinsers’ place on a dip of 60° towards the southeast. This dip is immediately reversed and succeeded by the lower Salina shales, until crossing Lost creek at Burgey’s saw mill, the Ore sandstone again shows in Lost creek ridge on a 15° northwest dip. In this portion of the valley therefore the upper Salina lime-shale formation has no representation and are not exposed until Lost creek is reached about a mile east of Kinsers’ place.

The Lost creek section through Slenderdale ridge about 2½ miles east of Laurel run is but slightly more satisfactory as far as actual exposures are concerned

J. Tennis has run a small drift into a fossiifossil [sic] ore bed on the north leg of the anticlinal upon a small tributary of the main creek, which has also notched the northern side of this ridge. The drift is now badly fallen in, entirely obscuring the ore bed, and is located just at water level a little south of the Slim Valley road. The Ore Sandstone is not well exposed here and in addition to being thin, is likewise very shaly, so that the ore-drift may have been located upon one of the Danville ore beds although generally reported to be the Sand Vein.

It was not possible to inspect the ore bed at this point, although it was evidently of good size, and dips about N. 15° W. 40°. The gangue rock thrown out from the opening is highly fossiliferous, brownish white in color and possibly represents the sand-rock underlying the Sand Vein.

In the main gap the Ore sandstone is equally obscure, although many bowlders of it, making large blocks, were seen at the bend of the road near Trego’s S. M. This dip was obscure; but upon rounding the little ridge further west on the Adamsburg road the underlying argillaceous slates and blue clay rocks dip distinctly N. 20° W. 60°, just east of E. S. Auker’s house. Underlying red and brown shales show further south on a 40° southeast dip, and on the south side of the anticlinal, until just north of Wedman’s place, the southern outcrop of the Ore sandstone is distinctly marked by a great number of loose blocks of sandstone. Still further south and nearer McAllisterville, there is a good exposure of the upper Salina lime shales
