I came over the Dakota cylmudite after passing over the crest which dived down into a valley which has the dinosaur horizon and on the other side of the [illegible] the Dakota cylmudite upon the continuation of the hill instead of going on Freeze Out but passed down the valley north and west along the great ravine westward. Here my attention was attracted to large mass of sand- stone. I then concluded to climb the ridge facing the setting sun and inside the section on the previous page. I was partly surprised to see that here the dinosaur horizon instead of being shale throughout has at least a foot or two of heavy bedded sandstone. Here as elsewhere the marine Jurassic holds its position. The four fossils gathered are also in the section for this horizon. The thickness here appear to be the same as at Como Bluff. The character of the beds and facies of the so called fresh water deposits are different.
