Know Your Local Geology!!! The Tabler Quartet

Mark & Kim's house also lies atop Louisville Limestone from the Middle Silurian. However, just off to the east you will find Waldron Shale indicated by the narrow gray strip & Laurel Dolomite (pink). Both of these are also Middle Silurian. The orange is the Drakes Formation (Upper Ordivician). The small brown area east of Edgeland Road is fill. I am curious to know what the fill is...gravel?

"Drakes Formation (0d).-The Drakes Formation consists of four members: Rowland, Preachersville, Bardstown, and Saluda Dolomite Members. The Rowland and Preachersville occur in the eastern part of the Outer Bluegrass region, and the Rowland, Bardstown, and Saluda occur on the west side. The Drakes Formation is composed of dolomite, limestone, mudstone, and shale. Dolomite, dolomitic limestone, and mudstone are most abundant and are commonly composed of silt-sized grains, are sparsely fossiliferous or unfossiliferous, partly laminated, and locally mud cracked and ripple marked. The Bardstown Member, which makes up only a small part of the total Drakes, is composed of fossiliferous limestone in irregular or nodular beds thinly interbedded with fossiliferous or sparsely fossiliferous shale. The Drakes Formation generally ranges in thickness from 20 to 150 ft. In south-central Kentucky, it is locally cut out by the unconformity at the base of the Devonian rocks."
