The "Index" or key of the map references the first two wells of the Standard Oil Company, other oil & gas wells, the lands of the Standard Reserve Oil Company, the lines for the Chicago Burlington & Quincy Railroad (red dashed line), the Union Pacific Railroad Main Line (solid red line), and certain county and other roads. On the far right portion of the sheet is a large schematic cross-section showing "the stratifications of oil sand encountered" in drilling the Union Pacific Oil Well.
Oil was known to exist in Wyoming long before the present map, since at least the 1830s when Captain Bonneville found an oil spring near Dallas Dome. Uinta County was known to have oil near Hilliard when Fort Bridger was established nearby in 1842 (both appear on the present map). Yet, this map is one of the earliest depictions of the industry on a promotional piece, produced when the railroad, the automobile, and the motorcycle created explosive demand for oil. Overall, the present map is testament to the importance of southwestern Wyoming in the history of the oil industry. Wyoming still ranks in the top ten among oil-producing states in the U.S.
