Nelson County - Bardstown East of town, along the Creek 48 An east and west road runs through the town, past the Court House. East of the town it turns northwest, and crosses the creek. A hundred feet south of the bridge Tetradi-nina minima is found in a soft blue clayey bed about 1 foot thick. This is the high- est unquestionably of Lower Silurian age. Above the Tetradima bed is found 1 foot of thin bedded shaly limestone, very charac- teristic of this horizon even where the underlying clay does not contain Tetradi-ma. It is well exposed at Buffalo Creek, two miles west of Bardstown. Above the shaly limestone lie 25 feet of a clayey, or fine grained areaceous looking limestone of brownish color. The lower 5 feet are not as well bedded as the overlying portion, and no fossils have been found determining their age.
