Fig. 5 in An Early Miocene Dome-Skulled Chalicothere from the ''Arikaree'' Conglomerates of Darton: Calibrating the Ages of High Plains Paleovalleys Against Rocky Mountain Tectonism

Fig. 5. Redrafted version of N.H. Darton's cross­section (1899: fig. 213) from Spoon Butte to Sturdivant's Ranch, showing the silica­cemented sandstone caprocks descending in elevation to the south. Darton regarded all the caprocks as ''Arikaree'' conglomerates, ''consisting in large part of crystalline rocks and apparently lying on a steeply sloping surface''. The letters A­E were not explained in his caption. Note correspondence to figure 3.
