ID. Campbell, M. R. 1754Click on photo for higher resolution. Panorama with image 1753. View of rocks exposed at the upper end of the town of Morrison as seen from the Turkey Creek Road just above the town. The rocks shown in this picture extend from the Dakota forming the hogback on the right down through the Morrison and Jurassic to the Carboniferous. The top of the Carboniferous shows near the base of the Hogback on the east, but its most prominent member is a big white sandstone over the cottage on the right. The sandstones on the left are of deep red or maroon color and they appear to rest on the crystalline rocks of the Front Range, as shown in the picture. Jefferson County, Colorado. 1926.
