"Knight saw Dutgan and Mr. Fulmer collected Merifer cameratus. The age of these hills is therefore Upper Carboniferous. These hills lie at the base of the Laramie granitic hills and both maybe covered by the Tertiary. I have no doubts that the moss agates which are found in the Tertiary near here or further were derived from the Carboniferous. In the afternoon went to the "Red Hills" 1/4 h. at about 3 miles of this camp. Here we also found calcedonic stalactites but more finger shaped, he saw no fossils but I have no doubts that these brick red hills lie above the Upper Carboni- f erous and maybe either Permian or Triassic. This inference is based on the dip of the Carls. See in the morning. Collected about 400 pounds of minerals today.
