Diagram of section of Belly River (Upper Cretaceous) along South Saskatchewan River. After Hind, 1860. Copied from a book. Pioneer Geologists in Saskatchewan.

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

Section showing Whitemud Formation at base overlain by both sand and clay facies of Frenchman Formation in which channelling can be seen. Above the greenish and yellowish sands of the Frenchman lies the basal Ferris coal seam of the Ravenscrag (Paleocene) Formation. Ravenscrag Butte, Saskatchewan. May 1964.

Section through ejected lava block to show different texture in centre than on rapidly cooled outside. Near Myvatn. August 4, 1960.

Section through rimmed kettle showing superglacial till over basal till with sharp contact at right. Near Ardrossan, Alberta.

Section through soil polygons on top of till filled by sand (partly white). Trans Canada pipeline trench.

Earthquakes. Section through the centre of earth showing the wave paths (firm lines with arrows), and arrival times (in minutes reckoned from zero time of the shock). Since there is a shadow zone free from P and S waves for wach such earthquake, it is inferred that the earth has a core which refracts the deeper waves as shown in the diagram. Holmes, 1953, p. 374.

Cross bedding. Sections to illustrate current bedding and its values in determining whether a bed is right way up or upside down. A) the current-bedding structure is complete B) the upper part has been eroded off down to AB. The truncated current-bedding pattern is right way up C) the truncated cross-bedding pattern is upside down. Holmes, 1953, p. 95.

Sediments in the ocean. Location of cores with sand and silt layers (shaded areas) found on the deep floor of the Atlantic Ocean. Shepard, 1960, fig. 84.

Seismic structure map (Carter Oil Co., 1944, reconnaissance)on top of Palaeozoic rocks, Cantaur field.

Seismic structure map on top of palaeozoics, Mooze Jaw area, SK.

Seljalandsfoss. Waterfall plunges from the edge of overhanging cliff, 80 m high. August 9, 1960.

Sequence in the development of a kame terrace. Ice wasting from an irregular topography lingers longest in the valleys. While the ice still partially fills one of these valleys, outwash may be deposited between it and the valley walls. The final disappearance of the ice leaves the outwash in the form of terraces along the sides of the valley (Leet and Judson, 1958, p. 249).
