 thickness estimated: ((Drawing in field book of layers folded upwards and with descriptions intercalated into the drawing. Numbers from top to bottom)) 1) Sandstone nearly white 10 ft weathers buff massive. 2) Very hard fine pearl gray ? 6 ft massive. 3) Pink thin bedded sandstone, partly cross bedded weathering red 30 ft.? 4 and 5) Very fine grained calcareous sandstone, massive, violetred (?) 30 ft? 6 and 7) Very fine hard clay, slightly effervescent, whitish, 6-10 ft. 8) Pink sandstone, thin bedded weathering red 15 ft massive below. 9) Very fine grained massive sandstone white 9 ft. Apparent dip flatter in actual face of cliff because exposure short.

We measured one face of 20 ft. and from that estimated the whole cliff at 100 ft. Big hill north of fold, in syncline is Lykins at base, dark red and regularly bedded below, lighter red and massive, light pink and very massive in the upper part which forms a bluff. Red and pink massive part about 150 ft in thickness. Above this are about 250 ft. of light colored (mostly gray) limestones and sandstones and clay shales of Morrison age. Above this the slope to the top is covered by Dakota sandstone and conglomerate debris, none in place. Below this exposure we find the red sandstones to the Lyons ridge except for one white band about 20 feet thick everywhere present. Saw 2 white throated swifts on above mentioned hill. On way back we roughly estimated that there is about 200 feet of Lykins below the
