Figure 2-8. Photograph of the Pounds Sandstone in Garden of the Gods State Park (SW1/4 NE1/4 NW1/4, sec. 36, T10S, R7E, Saline County, Illinois). The lower part of the outcrop exhibits tabular planar cross-bedding typical for this unit. Contorted lamination in the upper half of the view represents rapid dewatering of the sand. The staff at the base of the cliff is 5 ft (1.5 m). © University of Illinois Board of Trustees. Photograph by Scott D. Elrick.
