A great example of this large, detailed, and colorful geological map of Texas. The legend names and locates seventeen different geological types through the use of color and pattern. The map is likely a compilation of earlier publications on the geology of Texas. Prepared by J.A. Udden, C.L. Baker and Emil Bose of the University of Texas. Very interesting vertical sections show in detail the various geological formations beneath the surface at four locations: Northern Trans-Pecos, Southern Trans-Pecos, Llano Estacado, and Central and Coastal Plains. This updated 1919 edition shows a redefinition of the Cretaceous rocks in some areas when compared to the 1916 first issue. This map should show the 1917 addition of Hudspeth county from part of El Paso, but it does not.
