This diagram is intended to be used asa guide in teaching the physiography 4) 
geology of the United States. The topographic features are expressed with the it) 
of revealing or suggesting the underground structure, and the general character] 
the underlying rock. 
An introductory drill such as having students draw cross sections through 1) 
Adirondack uplift, the Cincinnati or Nashville Domes, across the Appalachians) 
different places, through the Black Hills, Central Texas, the Ozarks, Wisconsin a 
many other regions is followed up with the use of other available material, es} 
cially state geological maps and the United States Geological Survey topograp! 
sheets. 
The student frequently fails to note the significance of a locality with relation 
the physiographic province or geological region as a whole. This is overcome | 
requiring the student to locate upon the diagram the position of the topograp|, 
quadrangles under consideration. As practically every topographic map publish) 
by the Survey was consulted in the preparation of the Diagram, most of the signi 
cant features are recognizable in the Diagram too. Seventeen geological proving 
are discussed briefly on the map.
