(a) Maxey Ranch, locality ‘O’; note thickness of basal palaeosol, prominence of quartz-kaolinitic siltstone, and weathered channel sandstone boulders. (b) Maxey Ranch, locality ‘O’, detail of erosionally resistant quartz-kaolinitic siltstone and overlying organic shale. (c) Maxey Ranch, locality ‘O’; note lateral continuity of beds. (d) Lycopod B, locality ‘K’; note both upper and lower coal intervals. (e) Squaw Mountain Coal Mine, locality ‘H’; note interbeds in transition between organic shale and floodplain mudstone. (f) Coal Mountain, locality ‘A’; note size of channel sandstone-dominated ridge in background.
