Shutter ridges. Billings, 1960, p. 393.

Buckling associated with strike-slip faulting. Billings, 1960, p. 393.

Section from centre of a continent to its margin showing ideal arrangement of lowlands and mountain belts. King 1959, p. 5.

Columnar section showing sequence of Palaeozoic and Precambrian formations in the Grand Canyon and their topographic expression. King 1959, p. 51.

Geologic map section of Crazy Moutains, southwestern Montana showing Livingstone formation of latest Cretaceous and Palaeocene age, and the stocks and dikes which intrude ot. Dotted lines above the setion indicate the volcanic field that probably lay on the site of the Crazy Mountains in Tertiary time. King 1959, p. 103.

Section showing structure of the Grand Canyon. Section from El Tovar northward to Kaibab Plateau. King 1959, p. 103.

Map of southeastern Pennsylvania and eastern Maryland showing sedimentary rocks of Newark group, and dikes and sills of diabase which intrude both the Newark group and the earlier crystalline and sedimentary rocks of surrounding areas. King 1959, p. 51.

Settling velocity of quartz particles in still water, plotted on double logarithmic scale. Experimentally determined velocities are represented by small circles. Dunbar and Rodgers, 1957, p. 5.

Map of California showing topographic provinces and the principal faults. 1. Ocean, with approximate edge of continental crust indicated by dotted line. 2. Major mountain areas. 3. Lowlands and minor mountain areas. 4. San Andreas fault. 5. Other high angle faults, active or recently active. 6. Inactive high-angle faults of earlier systems. King 1959, p. 165.

Structural map of North America. King 1959, map at end of book.

Block diagram showing stages of erosion of a mountain in the Basin and Range province. An initial fault-block form is assumed in stage A, but successing stages might have developped from any initial tectonic form. (A) Fan-free and Fan-based, (B) Fan-dented, (C) Fan-bayed, (D) Fan-frayed, (E) Fan-wrapped, (F) Pan-fan. King 1959, p. 155.

Laminar and turbulent flow in stream. Velocity is indicated by the relative length of the flow lines. Dunbar and Rodgers, 1957, p. 5.

Role of turbulence in keeping sediment in suspension. The concentration of sediment is greater near the bottom and progressively less upward. The ascending eddy (A) therefore carries more sediment per unit volume than the descending eddy (b). Dunbar and Rodgers, 1957, p. 6.

Graph showing velocities at which different size grades of sediment will be eroded, transported or deposited, plotted on double logarithmic scale. Dunbar and Rodgers, 1957, p. 5.
