Shale a little gypsum. A small draw above the well shows yellowish, 
blue and slate-colored shales for 70 feet, above which the slope is 
covered for 40 feet when a stratum of coarse brownish sandstone is 
reached that probably continues to the top of the buttes which are 
capped by prominent ledges of Dakota sandstone; see figure 10.
