Measured sections of Upper Ordovician strata in central Kentucky
The following sections in central Kentucky (fig. 1) are part of the data used in our studies of the Upper Ordovician rocks of Kentucky. The studies were part of a geologic mapping program by the U.S. Geological Survey in cooperation with the Kentucky Geological Survey. Where not otherwise noted, sections were measured in the field with Jacob staff and tape. Color names with numbers are based on comparison with the rock chart by Goddard and others (1948).
