same as true all the way down, the conglomerates predominating. Lenses of fine grained sandstone occur in coarse conglomerates, thus ((drawing in field book)). Fountain very thick here. Creek bed affords most nearly complete exposure of entire Fountain section I have seen. At or near base found a few chert nodules similar to those at Box Elder, but no fossils in them. Found none elsewhere in the formation.
At 4-Mile crinkled sandstone is 250 feet above Lyons with good exposure and no indication of light colored ridge making sandstone found in lower Lykins from St. Vrain northward. Reached home at 5:30 p.m., very tired. An almost cloudless day, which would have been very hot were it not for a brisk, cool breeze which made itself manifest except in well sheltered places.
