Figures 1(a) and (b) show two spacing histograms for compaction bands; (a) for bands at high-angle to bedding and (b) for bed-parallel bands at low-angle to the horizontal plane, both within Aztec Sandstone cropping out in Valley of Fire State Park, Nevada. The spacing values vary locally from a couple centimeters in the lower left to about 35 cm excluding the outlier.
