Cross Section of the Upper Elkhorn Coal Zone Between the McDowell and Jenkins West Quadrangles

This cross section shows lithic variation and coal-bed correlations for the interval between the Upper Elkhorn No. 1 and the Upper Elkhorn No. 3 ½ coals in eastern Letcher and southern Floyd Counties. It is one of a series being made to document the characteristics of the Upper Elkhorn coal zone in eastern Kentucky. The data are derived from the KGS coal borehole database, which contains records of exploration core holes supplied by coal companies. Lines on the diagram show general bed correlations and indicate places where mineable coal beds split into two or more thinner benches. The vertical alignment of logs is best fit to minimize structural and interval thickness variation along the line of section
