Death Valley National Park, California. Furnace Creek Formation at the north end of the Black Mountains. View is southwest and west of Zabriskie Point, an overlook by Highway 190 about 3 miles up Furnace Creek Wash from Furnace Creek Inn. The base of the Furnace Creek Formation is at the topographic break between the badlands and the rougher, higher ground in the distance on the left. Light-colored playa beds about 2,500 feet thick extend to the base of a conglomerate which forms the dark cliff at the right. The beds are dipping to the right (north) into the Texas Spring Syncline.

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.
