Quartz overgrowths on sandstone grains after clay formation, Nanushuk Group. Quartzose grains have overgrowths at points of low pressure (pore space) adjeacent to areas that were probably under high pressure (grain contacts). Overgrowths probably develop where clay coatings are absent. A polycrystalline quartz grain (upper left) has a pod of kaolinite growing on its surface. Sample 78ACh23, Kurupa anticline; magnification, 6.3 x 10, photomicrograph. Central North Slope, Alaska. Published as Figure 47A in U.S. Geological Survey Bulletin 1614. 1985.

Colorado National Monument, Colorado. Eastern end of Kodels Canyon Fault on the west side of Fruita Canyon. There is no visible displacement except for considerable thinning of Wingate Sandstone. The high cliff of Wingate Sandstone on the left rests on slopes of Chinle Formation. The pinon and juniper-covered slope near the middle is Kayenta Formation resting on thinned Wingate Sandstone. Entrada Sandstone forms the low cliffs on the right. Circa 1950. Figure 32, U.S. Geological Survey Professional Paper 451.

Glacier National Park, Montana. Altyn Limestone in the lower slopes of Appekunny Mountain, northeast of Many Glacier Hotel. This view is at the type locality of the formation, close to the site of the former settlement of Altyn. The Lewis overthrust is at the base of the cliffs, and the smooth slopes below are underlain by shale of Cretaceous age, which yields few outcrops. July 6,1901. Figure 2, U.S. Geological Survey Professional Paper 296.
