This is a gigantic 1929 Willard Rouse Jillson geological map of Kentucky. The map depicts the state from Missouri to Virginia and West Virginia and from Ohio, Indiana, and Illinois to Tennessee. Highly detailed, the locations of seventeen different geological formations are traced across the state using different colors and patterns to identify each individual formation. A legend situated in the upper right quadrant presents the seventeen different formations and which color is associated with each one. Fault lines within the state are also noted and marked by green lines. Coal mines and rock asphalt mines are also identified, as are productive oil and gas fields, which are marked by red areas filled with parallel lines. Each field is numerically identified and corresponds with an index situated in the upper left quadrant. Five different geologic cores are also included in the upper left quadrant, allowing the viewer to see the different layers of rock and other formations lower below the surface. A single core is included along the right border as well. Two profile sections of Kentucky illustrating the layers of formations from the side are included along the bottom border.
Within the state itself, counties are illustrated and labeled. Myriad cities, town, and villages are also labeled, including and Lexington and Louisville. Power transmission lines across the state are illustrated in blue, with eleven different patterns used to differentiate between the lines owned by different power companies. Railroads throughout Kentucky are illustrated and labeled as well.

The United States Geological Survey (1878 - Present), aka the U.S.G.S., is a scientific agency of the United States government, which was founded in 1879. USGS scientists study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines: biology, geography, geology, and hydrology. It is a bureau of the United States Department of the Interior and is the department's only scientific agency.
