Summary:
Marsh Creek Sandstone Tongue (new name) of Lee Formation mapped in Hollyhill quadrangle. Consists mostly of light-gray quartzose fine- to medium-grained thickly cross-bedded sandstone that weathers pink, brownish yellow, and brown. Locally coarse grained and sparsely conglomeratic. Upper and lower few feet commonly fine grained, thinly ripple bedded, and platy. Contains thin shale lenses locally. Thins southward and pinches out in Marsh Creek valley north of Clear Creek and probably south of Pleasant Run. Tongue is conformable with shaly units of Breathitt Formation immediately above and below. Thickness 0 to 150 ft. Tongue is not shown on Cumberland Falls side of the border with Hollyhill, but may be equivalent to a mapped sandstone in the Lee in this approximate stratigraphic position farther north in Cumberland Falls quadrangle. Age is Early Pennsylvanian.
