upper half and in the upper half of the are two thick nodules grows. Chest is common in the upper half but here it is not con- spicuous. I am sorry very near and then, for nothing of value. The Coconino is extraordinarily forest here, and at times is decidedly crum bled. It is in the lower third where the Styrcehalian tracks seem. And they have exposed by areas of the sandstone on them and made a stone steps beside small to traverse them. One series of tracks is continuous that leads with foot. Large good specimen. I did not see -- none as good as the one must at Yale. It is at this place that Daile quarried out the lot he sold to the University of Arizona. The Coconino - Hermit is a sharp con- tact. The former is a yellowish white fresh sandstone resting upon a deep red sandy - muddy shale. From the trail one could see about 10 sandstone dikes like those of the South Angel Trail. The Hermit - Supai contact where a markedly eroded me. The thinly-beded sandstone of the Supai are deeply pitted -- as deep as Sufut- and it is at Red Top in me I there that the Permin plants and styrcehalian tracks come from.
