,

Instead of attending commencement and taking my B. A. degree I started north on foot, up the Lykins lateral valley NW of. There the Lykins extends up well on the flanks of the Lyons, with Fountain at top of second hogback. Morrison sandstones, limestones and clays (latter partly calcareous) pretty well exposed. In middle of Dakota shales 2 miles N found a stratum filled with plant fragments and a few poorly preserved fish scales and vertebra. Here medial sandy shales are 90 ft. thick between the well defined walls, dip E 80˚. In the crinkled sandstone and accompanying limestone are within 135 feet of the Lyons. Lyons is about 100 ft thick. Top of Fountain contains alternating sandstones and conglomerates
